This bearing roller is perfect for scoring thin sheet metal. You can create a fold by placing it on a soft surface like a rubber mat and pressing down. It can also be used for folding cardboard or creating creases. There may be some burrs or minor scratches, but they should not affect usability. Although it is unused, it will be opened once for inspection before shipping. The blade thickness of the roller is 0.5mm. (Total length 170mm, wooden handle length 115mm, roller diameter 35mm) It is also listed elsewhere, so it may be removed without notice.
