Ask a Question
  • Is this suitable for stamps? I’m getting a clip on pair for my glasses to read small printed books and also a hand-held traditional magnifier but I need something hands-free and with a light for the stamps. I wear reading glasses. Thank you for a fascinating website!

    Yes, this one is good, linen testers are ideal for anything flat, especially stamps (also coins, linen, photos and prints). It works fine with reading glasses.
