One of the perks listed is a "personalised physical merch". What is this?
The plan is to make an exclusive piece of merch each month (art print, sticker pack, blindbox, apparel - who knows?) while adding some personal touch to every supporter of this level. And after gaining some traction and stability I hope to make my dream come true and create series of collectibles, so you may want to stay tuned, the ideas are huge.

While postal stuff is on me, this reward level requires you to stay in contact and share your postal information, so keep that in mind while choosing perks.
