Each has its own merits. Amber is more durable. If it is not easy to break and is crystal, it will definitely look good and be more delicate. It looks more comfortable. Lamina's words, Lamina mounting technology is a brand new form of art painting (image) mounting. It uses unique technology and modern polymer technology to mount the picture directly on the backing board. The backing board of the picture is integrated, like colorful crystals As bright and beautiful as its surface texture is unique, it presents a special effect like an oil painting. The picture is delicate and clear, smooth and not dazzling, and has a three-dimensional effect, which is highly appreciable. Because the drawing paper is completely isolated from the air, it has the characteristics of never fading, waterproof, sun protection, and scrubbing. Personally, I think Lamina is better.
