The bamboo slips are arranged in a horizontal line, with each slip having a different color and pattern. The colors range from light brown to dark brown, with some being darker brown and others being lighter brown. The patterns on the bamboo slips vary in size and shape, creating a sense of depth and dimension. The bamboo slips appear to be made of wood and have a smooth texture.
