Folding (linen tester)Origin / brand:
matt black Presentation / extras:
A linen tester (also known as a linen prover) is a folding magnifier, traditionally used for measuring the threads-per-inch on linen, which is why it has a scale marked around the base. Today, they are mostly used for viewing stamps, coins, prints and photos - anything flat. They come in all sizes from 15mm to 90mm, one even has a light.
Specifically, this one is large enough to rest over photos, postcards, prints etc, to study details in the picture, it's not too powerful (which would show you the dots that make up the picture).
