I bought one of these to go with my new Penny Changer, and I'm so glad I did! Talk about making life easy! The Tumbler is a nice, soft silicone material, and it very nicely isolates my squishier treats from the rest of the pouch. And of course the squishy treats are the favorites! When I get home, I can just close the Tumbler's top and put it in the fridge. Very cool!

Having this for my penny changer or sidekick is a game changer! Messy treats can stay contained and the silicone is easy to clean when done!

This is one of my favorite little add on accessories to use with the Penny Changer or by itself. It seals up nicely, I can stick it back in the fridge or freezer if I still have treats to use. I've also used this many times alone when we take the dogs out to a patio meal and it's perfect.
