Learn how to insert FIRESIDE Little Bottle Straws into your bkr Straw Cap and keep the silicone set clean with simple, supported steps.
Start with the right cap and bottle
The FIRESIDE Little Bottle Straws are designed to work with bkr's 250/500ml Straw Cap, which screws onto your bottle. Before you insert a straw, make sure you have that cap on hand—the straws pass through the cap's clear silicone valve, so a standard cap without the valve won't work the same way.
This set is the 500ml size, intended for bkr bottles that use a 500ml straw. If you're unsure which size your bottle takes, check the bottle's capacity first; the straws are also available in 250mL, 650mL, and 1L to match other bkr sizes.
How to insert a FIRESIDE straw
- Screw the Straw Cap onto your bottle: Twist the cap on until it sits securely. The cap is the part that holds the straw in place.
- Insert the straw through the valve: Push the straw through the clear silicone valve in the cap. The straws are angled for easy sipping, so orient the bend toward you.
- Sip and adjust: If the straw feels too long or short, check that you're using the 500ml size with a 500ml bottle. The set is sized specifically for that capacity.
Cleaning your silicone straws
The straws are dishwasher safe, according to the product details. For everyday use, that's the simplest routine: place them in the dishwasher and let them dry. If you prefer hand washing, use warm water and mild soap, then rinse thoroughly—though the supplied information doesn't include hand-washing steps, so the dishwasher is the only cleaning method explicitly confirmed.
Because the straws are made of soft silicone, they can collect water inside after washing. Shake out excess water and let them air dry fully before storing them in a clean, dry place.

When to replace your straws
The supplied information doesn't specify a replacement interval. Inspect your straws regularly for wear, such as cracks, cloudiness, or a loose fit in the cap. If you notice any of these, replace the straw. Because the set includes three, you can rotate them and keep a spare on hand.
