Punch 4mm

You can punch holes in your leather with this stainless steel punch.
This is particularly practical if you want to punch holes on a large piece of leather relatively far in the middle of the piece, where you would not be able to reach with the opening of a punch pliers. 

Use a rubber mallet and an old cutting mat or a soft plastic board as a base for making the holes. 

Note: Slight rust stains may occur on this tool due to the steel used and the way it is manufactured. To avoid rust stains, protect the tool from moisture. You can remove existing rust stains with a little vinegar and salt or a sanding sponge.
