This is a handmade item. I make each one with care, but compared to mass-produced products or the work of experienced handmade artists, there may be some imperfections. f(^_^; Gear parts are fixed to an aluminum case with adhesive, and a resin coating agent is applied on top. There may be unevenness in the coating or bumps from the adhesive. Please be aware of this beforehand. #steampunk #gear #pillcase
