Review on 🔧 YBEKI Bike Repair Tool Kit - Ultimate Bicycle Tool Set with Multi-Function Bike Tool, Chain Tool, Tire Tool, and Bone Wrench. Portable Tool Bag and 6 Month Warranty by Greg Anderson

Includes what is known as a "bone wrench". I used it to remove the wheels from my wife's bike. 15mm worked great on the front wheel. When I tried to unscrew the rear axle nut, the key began to bend. One of the cast aluminum blades broke under the pressure and could be bent. I only used my hand to turn the nut, no more than was intended. The rest of the package seems fine, just tucked under the seat.
