Where could I get custom made pens?

I would check with someone locally in your area. Most places who do silkscreen or embroidery do ASI as well. ASI is ad specialty they can put your business name or whatever you want on a pen,key chain,pencils,etc. They may have a set amount you might have to do though, most places will have a minimum order. Could be a dozen hard to say. Good Luck Embroidery Technician
