Fits the straw perfectly . Doesn’t move once you put it on . Keeps the dust out

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.

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