Tamiya Tools Modeler's Punch
This handy tool is designed to allow you to cut circular pieces of material from a range of materials such as a plastic plate (up to 0.5mm thickness) or masking stickers, removing the need for fiddly use of a modeling knife. The small pieces it cuts will be of great use for recreating detail on your scale models or even creating your own masking stickers for circular areas. 2 different diameter bits are included.
