6 Pcs Accessories for Stanley Cup 20-40oz,2 Straw Covers,2 Replacement Straws,1 Straw Brush,1 Boot Included, Silicone Straw Cover Caps Topper (Black)

Not leak proof but but does minimize the spill it’s easy to use they stuff do hold up but just make sure to frequently wash everything

I found a brand new Stanley at a yard sale but wanted to protect the bottom from dents and needed a new straw. This worked perfectly for my 40 oz Stanley. The straw covers easily come on and off but don’t fall off the cup. My water intake is super high right now due to my pregnancy so I’m constantly taking the straw covers off and on but there’s been no signs of wear and tear so far. For the price I definitely think it’s worth it for the amount of stuff that you get. Especially the fact that it comes with multiple straws and a cleaning brush

I got this for the bottom of my Stanley so it wouldn't be so loud on the nightstand in the middle of the night. It works great to help with the loud metal clank noise.

Even though I only needed the straw topper and the tumbler boot, this set was a nice deal for the price. It included two silicone toppers, a silicone boot , two tumbler straws and a Stanley straw cleaner. More than enough!!! I’m a happy girl

Great quality
