ALIEN TAPE Heavy Duty Double Sided Tape, Nano Tape, Feet Clear Adhesive Tape for Poster Photo Wall Decor As Seen on TV, (1 Roll - 10 Feet)

Alien Tape is really good. Just cut it into small pieces. It holds strong but if you make the pieces too big, it will peel the paint. Just 3 or 4 slivers along each edge of the frame and it will stay there as long as you want it to. https://a.co/d/0g22tCj7
