Trafalgar Perforation Gauge

The Trafalgar Series Perforation Gauge from Unitrade is a simple and durable tool for stamp collectors. It is made from strong plastic and is small enough to fit in your pocket.

It can measure perforations up to perf. 20. The gauge includes both metric and imperial markings, so it’s easy to use no matter your preference. The perforations are progressive, which makes it especially useful for modern stamps. This is not a clear gauge, so it is better suited for use with uncovered stamps.
