I've taken pages from Gray's Anatomy and re-purposed these anatomy and medical images into 2.25 x 3.75 inch envelopes. These cute envelopes run are mainly black and white, but a few may have red as well. You will receive 10 of these cute guys for your crafting or gift giving. They fit Gift Cards PERFECT! Use for Christmas Gift Cards at the Dr's office or Hospital floor. Use for Halloween give away. Re-purpose for your art or paper crafting.
