1. ✅ SOLVED Whats this hairy thing?

    What's this hairy thing? Marked: 2 1/2 single. Nothing on back. Found in manilla envelope marked the same. Is this a paintbrush bristle sample or factory / salesman bristle sample? Brush for a photograph records? It's 3.75in width and flat. Any guesses?
  2. ✅ SOLVED I have no idea what this is? Found on path to Stinson Beach, CA

    At first I thought it was a comb. Then I saw that there were nails rather than bristles. The other side appears to be stone. I live in Northern California and found it on a trail leading to Stinson Beach.
