Sculpey clay Classics 12 piece Multipack, Never opened

This is completely sealed and has never been opened but was ‼️BOUGHT YEARS AGO‼️ so I’m not sure if they’re still usable! They feel very dry and firm when pressing on them, but an Internet search says Sculpey doesn’t dry out over time (but can get tough/need reconditioning?) I’m unsure how true this is as I’ve never tried. Please be aware if you buy this that this clay is very old and was bought years ago! (Probably 8+?) Cash and pickup only please.
