This is a unique bear bell, a compact bear bell made of natural antler and metal. It's a one-of-a-kind bear whistle from the brand K.blood.package Stag. The Explorer logo and serial number look cool. I bought it, but I haven't had a chance to use it, so I hope someone will. I remember the retail price was 6050 yen + shipping. As a bonus, I'll include a Chums bear bell (2000 yen) and a non-sale Montbell pin badge. Thank you for looking.
