Instant purchase welcome. 55-57mm can badges recommended. The photo shows a 56mm badge. (Chains and can badges are not included in the product) The can badge attachment surface has a ribbon for the safety pin and a magnet. There is a ribbon on the back for attaching chains, etc. I am careful, but it is handmade by an amateur, so there may be unevenness or traces of adhesive. Please understand this when purchasing. I am not currently accepting custom orders m(_ _)m #Rosette #Itarozette (Pain Rosette) ▼Click here for a list of rosettes for sale #hiropp_Itarozette
