Have a nurse in the family? Need a little gift? These are great!!! So cute and super functional for any large straw drinkware.

I give this product 4/5 stars ONLY bc I’m sad they are a bit lose on regular sized straws but other than that they are literally PERFECT for thick Stanley straws or smoothie straws (yellow straw in Pic) . The quality feel's strong and not flimsy at all.

This is the cutest straw cover I have seen. For the money I got the white and pink clouds. This isn't my Stanley it's the DD cup yet fits all those straws. Plus keep straw clean. Great buy
