Beautybio Glopro At-Home Microneedling Tool

Beautybio Glopro at-home microneedling tool with red light. Head is brand new, hasn’t been used. The handle itself vibrates and lights up as it should but the actual handle shows some signs of wear/discoloration around the silver parts at the bottom - tried to show in the last two pics. Also reflected this in the price as retail is $199.
