Bow Wow Key (Chìa siết/nới Bow Wow buddy)

This is a tool to help you easily tighten and loosen the Bow Wow buddy by Bow Wow labs (bully stick holder). The holder is a great idea, but can be tricky to get tight enough that the stick can't be pulled out and when you do it get tight, it can be difficult to loosen. This tool makes the job super simple.
