The 10 Pack contains ten Heavy Hex Gauges made of plastic laminated cardstock. These are packaged in a clear gift box for storage. The gift box is the correct size to also hold your business card. Simply include it, to personalize it.
Every Foreman or Operations Manager should have a 10 Pack to hand out to the crew. It helps to eliminate trips back to the shop and competitors on-site from taking away work. It makes the right size known rather than working on a "best guess" basis.
