Looked up Springfield and cost is a concern. Around $11-12 each. I do not charge for the wallets or belts so I am trying to keep cost to a minimum. I am retired, fixed income and do leathercrafting as a hobby so the cost per item is a concern. At the last visit by my American legion Post I did 30 wallets and around 25 belts. The vets were really thankful for them. Would like to continue to do it and also include the homeless vets of WNY. Last year I did buy a 12 pack of pre made interior that had three credit card slots on each side, when sewed it had two hidden pockets. Unfortunately Indo not remember where or who I got them from. Thanks for your suggestion
