To purchase this on Amazon click on the picture

This RSPIC lid is for 30 oz tumblers. It fits other tumblers as well, I have a Simple Modern 30 oz tumbler and it fits it perfectly. Not hard to get off of the tumbler either like the actual lid that came with my tumbler. In the opening has a straw area where it can sit. I wanted this lid since it actually closes and you can use it outside and not worry about bugs getting into your drinking or worry about it spilling either. It's easy to clean and even dishwasher safe.
