Unfortunately there are no plans to expand my current set, as there is not enough demand for certain characters. The manufacturer I use requires a minimum of 10 pieces per design, so for a custom keychain I would have to go to a different manufacturer. Manufacturing costs for individual keychains + cost of design would come to around $40-$50. If I manufactured them at home, this would clearly be a different story. Unfortunately at this time I'm not able to offer custom keychains at an affordable price. If you would like me to design a keychain for you to be able to have manufactured for yourself I would LOVE to help you make a design. However actually creating the product for you is a bit out of reach for me right now.
