Vervangend deksel voor 30/20 oz Stanley Tumbler met zacht siliconen rietje, lekvrij, morsbestendig deksel voor Stanley Tumbler, vervanging Flip Straw Cover Compatibel 30oz Stanley Cup

Perfect, leak proof.

Good lid that matches my white Stanley cup perfectly, not just in colour but fit too. Great price for the quality. Seems to be leak proof too. Just helps add extra functionality to my cup.

This lid with the straw is a great choice for Stanley cup.It screws on smoothly and fits perfectly.I didn’t have any spillages or leaks from it.It’s easy to clean.I would highly recommend.

I received: Replacement Lid for 40oz Stanley Cup with Soft Silicone Straw, Leak Proof, Spill Proof Lid for Stanley Tumbler, Replacement Flip Straw Cover Compatible 40oz Stanley Cup (Creamy White, 40oz)Replacement Lid for 40oz Stanley Cup with Soft Silicone Straw, Leak Proof, Spill Proof Lid for Stanley Tumbler, Replacement Flip Straw Cover Compatible 40oz Stanley Cup (Creamy White, 40oz).I can state this this product DOES NOT LEAK. which is ace as my cup with its original lid leaked like a sieve. However, the drawback is you need 4500 millibars of pressure to get it to release any liquid. That is to say 450,000,000 pascals of pressure (One pascal represents the force of one newton per square meter acting perpendicularly on a surface) to get 30ml of liquid from the container. All that for a mouthful of juice. What can i say? it doesnt leak..or pour. Love that it comes with a straw brush.

Okay - so after spending a considerable amount on a Wednesday Addams themed Stanley mug (colossal sized jug!), I was thoroughly disappointed in the standard lid that it came with. Would often leak when tipped and had that strange side-to-side little plastic strip on the lid. This replacement has a silicone rubber lip and sits really snuggly inside the Stanley - no screwing, simply plug it down hard ... and away you go; no spillage in sight!! Awesome!!
