COLIBROX 3 Pack Thermos Replacement Straws for Thermos 12 Ounce(model F401) Funtainer Bottle with 3 Straw Cleaning Brushes

Fits ok so far but doesn't seem like it's an official replacement part. The straws themselves are kind of flimsy and the top part, although it fits, is slightly different in mold. Works but I wish I'd have known it wasn't quite the same.

These must be knock offs. Original straws have cut outs and the lid straw leaks from the sides and pours out of the hole instead of dripping slowly when inverted. The straw is also slightly shorter.

They lasted a few months and leaked from a tiny hole in the top. I thought I'd try saving a few dollars by going with an off-brand product, but with lasting just a few months I'll go back to the Thermos brand. The leaking alone was enough to switch.

Perfect! New life for our kids' favorite cups! One of these new inserts leaks from the vent hole, and it doesn't seem to have any sort of check valve or flap to keep water from leaking out when the cup is upside down, but the other two are fine. The brushes are unnecessary, but nice to have! I wish all cups could be made new so easily, and so inexpensively!

Perfect fit in the thermos funtainer. So happy this product saved me from having to buy yet another cup for my son.

Love the fact that there are replacements for this brand of water bottles and it comes with brushes to clean the smallest holes.

when they arrive try them on the thermos some may need to be cut down but an easy thing to do. i like the quality and number of extras.

They're great. Exactly what I needed. LOVE that I can just buy these replacements instead of having to buy a whole new bottle.
