Chrome-tanned Leather Marking Spacing Gauge Set

This spacing gauge is commonly used for chrome-tanned leather. It can hold a mercury pen, allowing you to draw on the leather surface to mark the cutting position. It's important to note that chrome-tanned leather behaves differently from vegetable-tanned leather, so a regular leather marker may not leave scratch marks on its surface.
