6pcs Silicone Spill Proof Stopper Set, Reusable Spill Proof Plug Spill Proof Straw Stopper with Straw Covers Tumbler Accessory Compatible with Stanley Cup 2.0 40/30oz (Cream Yellow)

These fit perfectly on my 30oz Stanley tumbler. They keep my cup from leaking when I’m trying to carry more than I should, super easy to clean, inexpensive, and don’t take away from my rose gold Stanley’s appearance at all. Definitely worth the buy!

i liked this product, it did help stop leakages. i got it in the white color and i use it mostly for the straw topper.

Product color does not match cream 2.0 like I was hoping. Thought that info might help someone else.

Really hope to stop the Stanley from leaking. It’s a little bit difficult to put on and to wash on a daily basis, but helps prevent spills.

Alles super

Very happy with the caps.

I only actually use the part that goes around the straw (filling in most of that large gap), and find this stops water splashing up onto my Stanley's lid while driving.I would recommend not using the round piece that attaches to the bottom of the lid, as this creates a blockage for air, which means drinking through the straw becomes more difficult and noisy. This is still worth the purchase without using that bottom piece.
