5" x 5" (13cm x 13cm) art card with envelope, printed in British Columbia on 100% recycled card stock. The interior is blank. Pictured is the Barn Swallow, a species that often lives in close association with humans, building their cup-shaped mud nests almost exclusively on human-made structures such as open barns, under bridges and in culverts. 25% of proceeds from these cards will be donated to Birds Canada to support their bird conservation efforts.

(Note: I am no longer using cello sleeves in an effort to reduce plastic consumption and unnecessary waste.)
