These are more than 10 years old. There are 45 pre-cut 5 x 7 glossy sheets plus 20 envelopes from Hewlitt Packard. I never got around to using them. One envelope has a pinch mark on its edge, maybe from a wayward vampire.

Be mindful that 10 of the envelopes are a medium brown and will likely need a black sharpie to provide enough contrast. Or if you know how to print off address labels from your contacts list all the better.
