The Dab Caddy tray fits most 30oz double wall stainless steel tumblers with the 'step down' shape (to accommodate cup holders), and is specially designed to suspend your 1 gram concentrate jars above the ice and keep your carefully extracted terps chilled for hours while traveling, or even just around the house when you don't want to have to get up in the middle of a sesh to go get or switch out your terps.
This is the tray ONLY! Tumbler is not included!
