@moonshinebrigade 's metalhead.club stickers did not make it through the Deutsche Post distribution center and we're sent back. The exact reason (maybe weight, maybe dimensions) is unknown, but the stickers might have accumulated / stacked too much.
So I invented this: MHCSSDS (Metalhead.club Sticker stack distribution system) 🧐
It keeps smaller stacks of stickers separate from each other using a wrapper and paper staples.
