Review on 🥤 Reusable Silicone Straws for Kids - Safe, Flexible, 7.8 Inches Long (4pcs) with Cleaning Brush - Fits 20oz and 30oz Tumblers - BPA Free, Eco-Friendly by Lori Aguirre

They fit but not sure how long they will last. One of the straws arrived broken but as I was going to cut it anyway I decided not to return it. I recently bought a travel mug with silicone straws and they are a lot thinner and weaker in comparison. I bought these for my son when he was giving up spill proof cups. I used them with straws for receiving and throwing as he chewed on the plastic straws for them almost immediately. They work well, they are very snug and it can be a hassle to put them in a cup, but they are so snug he can't pull them out which is nice. The little animal accents are cute but I didn't use them as I think he's of that age where they might end up in his mouth if they slip right off the straw. I might take them when he's a little older if those straws hold up.
