Can't say I tested these out myself, but followed a simple format for our promotion into colleges in our city. Hire some pretty girls to hand out a useful item BAM.
Unusual is not the word. Really interesting promo tool cheap enough to be worth a shot. Thankfully we target a male demographic so it was less embarrassing to hand these out
If only there was a smaller order quantity option, I would have put my own face on these so my friends could think of me when they "do it." I ordered bulk quantity though with my logo, and I think my customers will be thankful
