As the name suggests, this product named "RIM" is a simple picture frame with a rim around the forehead. A 1 mm thick and 5 mm high rim goes around the perimeter, which creates a small depth in the picture frame. By adding this edge and depth, the brilliance and three-dimensionality that runs on the edge quietly creates a work. You can also cover the inside of the rim with acrylic or put an acrylic box to decorate three-dimensional works. It can also be placed flat and exhibited using an acrylic box. The surface of "Matte Black" is coated with a matte coating of shot blasting, and it has a luxurious feel with the texture of aluminum. Winner of the Good Design Award in 2021.
