[About Acacia Wood] Each of SHESAY's acacia wood series is handmade by artisans, so no two products are the same. Acacia is dark brown in the center, but whitish on the periphery, so the difference in shades is clear. We want to take the variation of knots, grain, and shades as characteristics of the wood itself, use raw materials without waste, and value limited resources. Please enjoy the individual differences and expressions of the material itself. *Since the product takes advantage of the texture of natural materials, each knot, grain, and color intensity may vary. Wooden products are prone to scratches and may shrink, warp, or have some cracks due to changes in climate and environment. We recommend cleaning with a dry cloth. When wiped with water, the color may transfer. Also, avoid direct sunlight or direct air from air conditioners and heaters. It can cause deformation, discoloration, rot, etc. such as distortion. The surface is coated with the minimum necessary coating so as not to damage the texture and feel. Therefore, the color may be slightly uneven. Since all of them are handmade, there are slight individual differences in size, color, and finish, but please enjoy the texture that is not available in mass production.
