Blank slide mailers for holding 1 microscope slide. They're meant for safely shipping microscope slides, but the little cut-outs make lovely little archways or windows.
Note the little notch cut from the top right of the cover (when closed).
Set of 2 (just the chipboard mailers... no glass included).
Sample artwork is by Lenna Andrews also using images from the Midnight #2 and Cinderella Borders Collage Sheets.
