Revenue basis · Founder self-reported, unaudited (see source page)
€20,273 is a one-off crowdfunding total, not monthly revenue; there is no data on post-campaign store sales or repeat purchases, so sustained viability is unproven.
All figures are founder self-reported and unaudited (noted on the source page).
