Not at the moment. Sorry.
The policy for toys then and now are different. Duncan is treated as a toy company, so everything that gets out our factory needs to be tested. For caps customization — the testing will cost more than making the caps itself for special projects. We can’t even sell blank caps anymore even we want to.
The good news, we will have a lot of caps for sale in the future — featuring world champions, Duncan Legends (older crew) and current team members.
