Glass Water Bottle Kits Explained: Sip Kit, Kiss Kit, and Accessory Kit

Quick answer

A bkr Sip Kit is a 16oz glass and silicone bottle plus a set of three silicone straws and a straw cap. A Kiss Kit pairs a glass bottle with lip balm. An Accessory Kit is the add-on layer: straws, a balm holder, or a sleeve that makes a bottle you already own work harder. If you are buying your first one, start with a Sip Kit.

bkr sells three things that get lumped together as a glass water bottle kit, and they are not interchangeable. One is a bottle plus a drinking system. One is a bottle plus a lip product. One is parts. Knowing which is which takes about thirty seconds and saves you from buying the same thing twice.

Here are the questions people actually ask before checkout, answered one at a time.

What comes in a Sip Kit?

A Sip Kit is the most complete starting point. You get a glass and silicone water bottle with its original cap, a set of three Little Bottle Straws in matching colors, and a Little or Teeny Bottle Straw Cap. The straws are the same food-grade silicone used across the bkr line, so they are soft on the teeth and dishwasher safe.

The practical win is that nothing is missing. You can fill it, cap it, and drink through a straw on day one, then swap back to the original cap when you want a wide mouth. If you have ever bought a bottle and then hunted for a straw that actually fits, this is the version that skips that step.

• Buy a Sip Kit if you want one purchase that covers bottle, straw, and cap.
• The straw cap replaces the original cap while you are sipping, so keep both in a drawer.

What is a Kiss Kit, and who is it for?

A Kiss Kit is a glass water bottle set bundled with lip balm. It exists because the two things live in the same bag pocket and get used in the same five minutes. It is the version people buy as a gift, because it reads as a set rather than as a single object.

If you already own a bkr bottle, a Kiss Kit is redundant unless you want a second bottle or you are replacing balm. If you are buying for someone who carries lip balm constantly, it lands better than a plain bottle because there is nothing else to add.

• Best for: gifts, first bottles, anyone who already carries balm daily.
• Skip it if: you only need the bottle and already have a balm you like.

What is in a glass bottle accessory kit?

Accessories are the parts that extend a bottle you already own. Silicone straws sized for a 12oz cup or a 16oz bottle, a silicone sleeve that adds grip and protects the glass, and a compact holder for balm when the bottle cap is busy holding a straw.

This is the category to shop when your bottle is fine but your routine is not. A straw that seals against the bottom of a cup is annoying; the bkr Little Cup Straws are straight with a slightly angled bottom specifically so they will not seal. That is a small design detail that changes how often you actually reach for the cup.

• Match straw size to vessel size: 12oz straws for cups, 16oz straws for Little Bottles.
• Buy accessories only after you know which bottle and cap you are using.

Which kit should a beginner buy?

Start with a Sip Kit in the size you will actually carry. 16oz is the everyday size for a bag or desk; 32oz suits long days and refill-avoiders. The 16oz Sip Kits are the ones most people land on because the bottle fits standard cup holders and the straw set covers a full day.

Add accessories later, once you know whether you drink through a straw or from the cap. Buying a sleeve and straws before you have used the bottle for a week usually means buying the wrong ones.

• First purchase: Sip Kit in 16oz.
• Second purchase: sleeve or extra straws, after a week of real use.

Are these kits good as gifts?

Yes, and the reason is that they are complete. A glass water bottle gift set works when the recipient does not have to buy anything else to use it, which rules out a bare bottle with no cap option and no straw. A Sip Kit or Kiss Kit both clear that bar.

Color is the real decision. bkr names its colors, and the kits come in specific ones rather than a full spectrum, so pick the kit whose color you would carry, not the one whose color is on sale. A bottle you like looking at gets refilled more often.

• Sip Kit for someone who drinks through straws.
• Kiss Kit for someone who is never without balm.

Can you build the same setup by buying separately?

You can, and sometimes you should. If you already own a 16oz bottle, buying the straws and straw cap on their own costs less than a second Sip Kit and gives you the same result. The kits are priced as a bundle, so the value depends on whether you needed every piece.

The honest tradeoff: kits are simpler and usually cheaper per item, but they lock you into the included color. Separate purchases cost more in total but let you match a bottle you already love. Neither is wrong; it depends on what is already in your cabinet.

• Own the bottle already? Buy straws and cap separately.
• Starting from zero? The kit is the better deal.

FAQ: quick checks before you buy

Do I need a Sip Kit or just straws?

If you already own a compatible bkr bottle, straws and a straw cap on their own give you the same drinking setup. A Sip Kit makes sense when you are starting from zero or want a second bottle in a different color. Check your cabinet before checkout.

Is a Kiss Kit worth it if I do not use lip balm?

No. The balm is the point of the bundle. Without that habit, you are paying for a set that duplicates a bottle you can buy on its own. Buy the Kiss Kit only if balm is already in your routine.

Which straw size goes with which vessel?

Little Cup Straws are made for 12oz cups and also come in 16oz. Little Bottle Straws are made for the Little Bottle. Match the straw to the vessel rather than trimming or forcing one to fit. Size first, color second.

What is the accessory I will actually use?

For most people it is a spare set of straws, because straws are the part that gets lost or left in a cup. The Jet Kiss Case is the one to add if your balm keeps disappearing into a bag. Buy the accessory that fixes a problem you already have.

Can I gift a kit without knowing their color preference?

The kits come in named colors rather than a neutral default, so color is a real choice. If you are unsure, a Sip Kit in a color they already wear is safer than an accessory that assumes a bottle they may not own. Gift the bottle, not the parts.

Kit contents at a glance

• JAMES - LITTLE BOTTLE SIP KIT 500ML (16 OZ): Opaque soft sage green glass and silicone bottle with a set of three James Little Bottle Straws and a Little Straw Cap. This is the full Sip Kit formula: bottle, three straws, and a cap, so nothing else needs to be bought to start drinking.
• HAVEN & THE SOUTHAMPTON - LITTLE BOTTLE SIP KIT 500ML (16OZ): Sheer tropical shallow sea green glass and silicone bottle with the original cap, three Southampton Little Bottle Straws in Jules, Haven, and Leo, and a Little or Teeny Bottle Straw Cap. The sheer colorway shows how much the bottle color varies between kits, which is the main reason to choose one Sip Kit over another.
• ERIS & THE MIDNIGHT CORDIAL - LITTLE BOTTLE SIP KIT 500ML (16OZ): Opaque black currant purple glass and silicone bottle with the original cap, three Midnight Cordial Little Bottle Straws in Eris, Mary, and Valentina, and a Little or Teeny Bottle Straw Cap. The straws are color-matched to the bottle rather than generic, so the set stays visually consistent after you swap caps.
• JET KISS CASE: Opaque black silicone compact holder made from the same food-grade, dishwasher-safe silicone as the rest of the bkr line; balm and compact container are not included. It solves the specific problem of where balm goes when the bottle cap is already holding a straw, and it clips to a bag strap or keyring.

Pick the kit that matches what you already own: a Sip Kit from zero, a Kiss Kit if balm is part of your day, and accessories once you know how you actually drink. Everything else is color.
