I actually buy these mailing labels for name tags for our Christian Cancer Support Group and they work great. I'm sure they are good mailing labels too.
I was trying to save time buy making special tags with a sponsors logo printed on them. They printed fine but the time I saved cutting cards was lost in using this Staples product where the business cards did not separate easily & left rough edges. The cards are also a little flimsy. I would not purchase this product again.
