Straw Replacement Compatible with Zak Straw Cups,4PCS 15 oz Tumbler Water Bottle Reusable Silicone Straw BPA-Free with Straw Cleaning Brush for Zak Designs Kelso 12 oz Cups

Loved how easily these were to replace and the fit perfectly. I didn’t use the straw part that goes in the cup. Since my little one is teething she would bite the silicone part and we have to replace them constantly. The inside original piece still works fine so we didnt need to replace that part. They have lasted long enough to be worth the purchase instead of buying a whole new cup and the colors were a good variation to match the cups we already had. So far no leaks and we have been using them for about 2 months. My little one is 2-3yrs and will continue to purchase when we need replacements. We do separate and put the silicone pieces into the dishwasher, or leave them attached to the lid while in the dishwasher. Please note, we have not used the clear inside straw piece or attempted to put in the dishwasher.

They fit perfectly on the Zak lidded kid’s tumblers.

On the contrary to some of the other reviews, this straw was a great replacement to the ZAK! cups! My 2yr old cut off the straw the first day he got it… so I had these delivered the next day and was pleased that they act exactly the same. The straw is no leak! The only difference is the plastic straw inside the cup is a clear harder plastic than the one that comes with the cup, but that doesn’t bother me

We have a bunch of Zak! Cups that my son has chewed or we have lost parts to. These fit and work great with them.

These leak like crazy! I wouldn't waste my money on them again.

Bought these as replacement straws for the ones my son chewed through. Not only did they fit his cups they’ve been leak proof and came in great color combinations.

Here's a concise version:_4.0/5 stars_A good replacement straws for Sak cups! Fit well, minor leakage when on its side (like originals). Only suggestion: straws could be slightly shorter to avoid touching bottom.Convenient extras for my granddaughter, who loves to chew on them.

Works as a great replacement to zak bite value and straw. Straw is the exact same length as original Zak straw.
