A prefabricated acrylic mirror with a bird silhouette as a motif. A small mirror that looks as if the back is transparent is completed by assembling simple parts of a flat surface. You can also enjoy it as an object like a sign that exists there. There are two types of mirrors, gold and silver. For the feathers, we matched each mirror with transparent colored acrylic that gives a sense of lightness. There is also a brass version that is textured with a technique called boiled color. Each of them has a different charm. In order to prevent warping, stains, and burrs on the mirror parts, we devise the production process according to the characteristics of the product, such as gluing them together and then cutting the parts.
