This is a used item, but its operation has been confirmed. I believe it's in good condition, but a 2mm part is missing. It was not possible to cut only the missing part. I believe the punch sizes are the common types: 2.0mm, 2.5mm, 3mm, 3.5mm, 4.0mm, and 4.5mm. The manufacturer and material are unknown. Cleaned and rust-proofed. The packaging will be simple, with the punch part protected.
