My wife has mixed it with coconut oil or something similar for an exfoliating scrub. Otherwise compost

We have had 0 issues with it. My wife and I both have one and they get used 5+ times a week, going on a couple of years now.

I’ve been using a 12 oz Yeti mug for years and love it. They also have an 18 oz version. Close the cap, throw it upside down in a bag and never leaks. Dishwasher safe and simple to use. I’d buy another in a heartbeat:Yeti 18 oz mug
