The Thumbhill introduces a new form factor and experience to the worry stone concept. We've found there is just something calming about sliding your thumb along the extended path and then meeting a smooth hill that then crest and quickly descends into a comforting valley. It's almost symbolic of our experience with stress, anxiety, and/or worry where it feels like the challenge of climbing a mountain and yet we must continue seeking the summit knowing an exhilarating and more enjoyable descent awaits on the other side. • Solid black walnut or hard maple with matte natural oil and wax finish• 550 lb Type III paracord lanyard or 30mm side push Titanium key ring• Designed and made in Lancaster, PA, USA.
