For mountain climbing, outdoors, hiking, nature walks, and bird watching. This is a pendant-type natural bird call. (People often compliment it, saying "This is nice!") Made with the bark of natural cherry wood. Cherry wood is known for its good sound quality, and this is a one-of-a-kind item. Total length: approximately 40 cm. If the sound deteriorates, you can revive it by finding a pine tree and applying a little pine resin to the sliding surface, making it a lifelong item. What you see in the photos is everything. Handmade item. #mountainclimbing #hiking #outdoors #wildbirds #birdwatching #pendant #keychain #birdcall #climb #birdwatching #cherryblossom
