EL Wrencho:
The Adjustable Box Wrench 
Rather than having multiple tools for different sizes and shapes of bolt heads, the adjustable box wrench offers ultimate versatility in a single, space-saving tool.
Perfect for car, bike, or home repair.
How It Works
The multi-layer construction means you can easily peel to shred sensitive details or private information from labels or documents. You can add extra levels of protection to tamper-evident solutions with destructive elements and peel-to-reveal hidden authentication codes, bar codes, or QR codes.
