Original Watercolor Art Card Print by Alberta Artist Brenda Neilson Made in Canada Artist/ Art Piece information is printed on the back of the card Inside is blank 5" × 7" card with envelope in a clear, protective display sleeve The PAPER...We print our cards on archival professional grade photo matte inkjet paper. At 11mil thickness and 232gsm, Premium Matte Plus is thicker and heavier than retail brand premium matte papers. The extra weight and thickness conveys superior quality and allows the paper to handle the heaviest ink coverage. The surface is ultra-smooth, non-reflective, and bright white. Acid free base stock. Acid free coating. The INK... is ultra-bright and smudge, fade and water resistant. The ENVELOPES...are ultra-white, acid free, and self-sealing (Peel off adhesive paper strip and press for a permanent seal- no need to moisten a gum seal.) The SLEEVE... has a re-sealable adhesive strip on the outside of the bag instead of on the flap (this prevents the glue from coming in contact with the card). The sleeve thickness is 1.6 mil, and it is archival safe.
