I recently purchased this reusable straws and my son is loving them. He has sensory processing disorder and he seeks a lot of sensory experiences. He loved to chew on them and they are holding up great! He has been sucking everything possible with these (yogurt, milk, smoothies) and it seems to be helping some of his oral sensory seeking. I have even been bringing these with us when we go out and he'll chew on it or blow air through them. They clean up very easily as well and have the perfect sized opening in my opinion.
This have surpassed my expectations!
