16 Pack Silicone Tips Reusable Straws Silicone Covers BPA Free FDA Approved Diameter 0.24" /6mm.External Diameter of The 0.35" Length 1.57"for Metal Straws Stainless Steel Straws

I bought this pack of silicone covers because it was advertised to fit both .25 and .33 sized straws. They arrived separated in two little plastic packages, so I thought the .25 size would be in one pack, and the .33 size would be in the other pack. No such luck. All 16 covers are the same size. Since I have multiple nesting straws, the two different sizes were very important to me. However, the 16 straw covers are all the same size and only fit the .25 sized straws. They fit the .25 sized straws great. Very snug, so no slipping. Difficult to remove, so it's a little hard to remove the covers in order to wash the straws and covers, but I'd rather have that than to have the covers slipping and sliding down the straws.I really like the colors included in the pack. I just wish I could use the covers on both the sizes of straws they were advertised for.

Helps my kids with safety because they walk around and drinking at the same time. She bites it so it does not last long. Very hard to put it over the straw. Have to use some strength.

Doesn't fall off like lighter tips. After losing 4 tips, bought these and they don't slip at all.

these are great, keep in mind they are a little difficult to get on. But to me that isn't a problem. seller was great

These are my favorite! Ordered three times over.

great for protecting your lip and teeth

Cool concept, do you make thinner straws?

Live these for my metal straws.
