Name Badge. Easy to make, inexpensive, laser engraved and cut wood badge.

Being a Subway owner and a maker, I've been doing my own
in-house lasered name badges for years now.
Easy to makes, 2-4 minutes/badge, depending on your settings.
Very inexpensive, under .20/badge.
Subway is by main, but I have done many other businesses too.
Keep as is, sand and paint, add gloss.
2 types: clip ($0.16 each) as shown and magnet ($1.00 each).
Got the clips from Staples: http://www.staples.com/Staples-Vinyl-Straps-with-Two-Hole-Clips-100-Pack/product_573105
