Straw Toppers for Stanley, Straw Cover Caps for 10mm/0.39inch diameter straws 30OZ/40OZ Stanley Tumblers, Food Grade Silicone. (5pcs-Basics-Green)

Very nice

These work perfectly and as described on my Stanley! Wanted these to cover up my straw especially going out in public places. Tight seal, easy to clean, pop off and put back on. Glad to have a pack of these as back up.

Not too hard or easy to slide on my 40 oz stanley. Will work good with my 30 0z as well. Secures my name plate that falls off easily. Soft silicone feel. Good quality! Love that multiple come.

Covers fit the Stanley straw very tight

👍🏼

We are in a humid tropic environment. I hate to think if anythink gets into my drink without noticing. So keeps your mind and bottles clear of any mishaps!!!!I have given as gifts and also put on our big purified house water!!!! It stays much cleaner.

Great quality for the price! Fit perfectly on my Stanley cup. East to put on and clean. I mostly wanted this because my toddler likes to grab my straw.

They fit Stanley straws and help keep drinks cold!
