I picked up this Opossum Rescuing is my Superpower Insulated Stainless Steel Tumbler and I'm really happy with it. The double-wall vacuum insulation keeps my drinks cold for hours, and the powder coating feels durable without being slippery. The laser engraving looks permanent and hasn't faded after several hand washes. It's sweat-proof, which is a big plus on my desk. The clear Polar Camel lid fits well. I also like that profits go to a fund helping Licensed Virginia Opossum Rehabilitators with vet treatment. Just remember it's hand wash only and not for the microwave.
