I sometimes get lip balms orders for a small quantity (less than 30 lip balms) and the customer will request the flavors be assorted, which results in a small order with 4 different flavor lip balms. Because I print my labels 15 to a sheet, I would hvae extras of each flavor when I printed the flavor right on the label. This tiny 0.5" circle label solves the problem! I make the entire order with no flavor on the main label, and slap one of these cuties on the bottom of the lip balm.
My only trick was finding a high quality (but tiny image) that would easily identify the flavor to the customer, and I was able to find what I needed from my usual clip art site.
