Why These Standards Exist
The technical requirements aren’t arbitrary brand control — they’re product integrity standards. Storage products for precious metals have to be safe for what they hold, structurally sound for stacking, and consistent enough that customers get the same experience regardless of which reseller printed their product.
Cutting corners on materials, magnets, or print quality damages the Coinfinity reputation for every reseller, not just the one who made the bad product. These standards are how we protect all of us.
