This is a small version of the Beretta Hand Gun Cookie Cutter I made and sell in my online store. Use this item to make cookies, cut fondant or use with clay or resin and make your own mold for candies or charms. I encourage you to make molds so you can make candies and charms to sell online anywhere you please! EnjoyI used a very expensive package to make an item that any company whom had paid for said package would be ashamed to admit. Even though said package was collecting dust on shelf anyway. As for printing: You know your filament best so you use what best suits you. I use PLA and print mine at .3mm @ 220.
