Can I sell my Digitalny Ziak device?

Kinda regretted buying my ipad 9 cellular 64gb and I think that money I could spend better and it isn't essential anymore for me cause I bought a gaming laptop recently. Mine is Jailbroken with dopamine and it has some perks so I think it could go for 300€-ish on bazos. I don't speak slovak and google translate doesn't emply that it isn't allowed (I assume it isn't but want to make sure)
