Holy **** this wax wallets are amazing. I have seen knock offs every where but knew they wouldn’t perform the same as the 420 science wax wallets. These wallets were engineered to be compact and reliable. The silicon top and bottom piece line up perfectly and creates and silicon pressure seal to keep all your goodies safe inside. Will fit a gram of concentrate no matter what form be it wax, shatter, live resins. I have 6 of the wax wallets now to give myself different flavors to choose from. Thank you 420 Science and cheers.
