The Re-Play silicone straws are a great addition to the Re-Play straw lid cups. They're made from soft silicone, and are translucent so you can see what's inside, and see whether they need a clean, and are very flexible, making them resistant to damage by chewing.
With a diameter of 5mm, they fit perfectly into the straw cup as well as being a great option for smoothies and thicker drinks.
Each straw is approximately 20cm long
Price is for single straw
