Abstract: Korner Keepers is a sticker having 3 cut outs at 12:00 o'clock, 4:00 o'clock and 8:00 o'clock. This apparatus is comprised of threaded laminated peel away stickers shaped especially for applying and conserving the corners of keepsake cardboard boxes as its name implies. The very middle and intact part of the self adhesive angel design is applied to the corner point of a box and the three flaps are pressed over the three outer periphery edges to facilitate improved reinforcement or repair of cardboard boxes containing items needed to be stored in their original, delicate packaging, such as games, puzzles, shoes, kits, etc., as the first functional embodiment. Further embodiments will include elongated stickers or sheets of same variation for light duty plastic and for the binders of paperback, hardback or school text books.
