Great replacements!
Perfectly fits my thermoflask 16 oz straw and lid bottle. Good price for pack of 4.

They Seal the Deal 🌀👌
They fit just right (compatible as promised), and installing them was a breeze — no wrestling, no weird stretching, just pop them in and get sealing. The material feels sturdy but flexible, and they’ve held up great after multiple uses and washes. Honestly, it’s the kind of purchase you don’t think much about until your old gasket gives up mid-smoothie and you end up wearing half your breakfast. These saved the day — and my shirt. Great value, solid quality, and now my blender is back in business. Would definitely buy again... but at this rate, I won’t need to for a while!

Too small for thermoflask
Did not fit 16 ounce thermoflask as advertised. Too small. Falls out, does not seal, leaks everywhere.
