I haven't a clue what this thing is but upon doing some googling it seems like it is some sort of vacuum heat press for a thing called sublimation for phone cases and things. Found it in a cupboard at my mums house while clearing out after her passing. I've plugged it in and pressed a few buttons and it makes a mechanical noise I presume forming the vacuum and it gets very hot but I don't know how it works or if it is missing any parts so take this into consideration this before buying.
