Learn how to properly insert, sip, and clean your bkr Demi Cup Straw Set with your 16oz glass water bottle for a leak-free, convenient experience.

Quick answer

To use a Demi Cup Straw Set with your 16oz bkr bottle, insert the straw through the cup cap opening, angle it slightly so the bottom doesn't seal, and sip. Clean the straws regularly with a brush to prevent mold.

Why Use a Demi Cup Straw with Your 16oz Bottle?

The bkr Demi Cup Straw Set is designed specifically for 16oz cups, making it a perfect match for your Little bottle. These straight straws have a slightly angled bottom that prevents them from sealing against the bottom of the cup, allowing for smooth sipping without airlock. They come in a set of three matching colors, so you can rotate or share them easily.

Using a straw can reduce spills when you're on the go, and it also helps protect your teeth from prolonged contact with acidic drinks. Plus, they're reusable and dishwasher-safe, making them an eco-friendly choice.

Step-by-step: Using Your Demi Cup Straw Set

1. Choose your straw: Select one of the three Demi Cup Straws from the set. Each straw is 16oz size, so it fits your Little bottle perfectly. All three straws are the same length; pick any color you like.
2. Insert the straw into the cap opening: Hold the cap of your bkr bottle and push the straw through the cap opening. The straw should slide in easily; if it feels tight, do not force it. The angled bottom will naturally point toward the side of the bottle. Never force the straw—if it doesn't slide in, check that you're using the correct 16oz size.
3. Adjust the straw position: Once inserted, ensure the straw reaches the bottom of the bottle without sealing. The angled tip should rest against the side, not flat on the bottom. If it seals, gently pull the straw up slightly or rotate it. A sealed straw means no liquid will come through; adjust the angle until you hear air or see bubbles.
4. Sip and enjoy: Drink as usual. The straw will stay in place while you sip. When you're done, remove the straw by pulling it out from the top. Rinse immediately to prevent residue buildup. Rinse the straw right after use to keep it clean and prevent odors.
5. Clean the straws regularly: Use a small brush (like a straw cleaning brush) to scrub the inside of each straw. They are also dishwasher-safe (top rack recommended). Dry thoroughly before storing to prevent mold. Neglecting to clean straws can lead to mold growth, especially if you use them for anything other than water.
