I use an old style, manual stencil machine. Place the oilboard in it and pull the handle each time for a letter/number. The 3/4" is an ancient Diagraph model. I can cut what ever stencil you need, especially caliber for ammo cans. If you use ammo cans, storage bins, etc. to store stuff, stencils are a great way to label what is in them. I use a lot of ammo cans for storage and like to mark the front of the can/container so it will be visible when on shelves, in a locker, or stacked. I can make custom stencils in 3/4” letters, let me know what you want. See my other auctions. I ship to the 48 United States only. PayPal only. Thanks
