When painting Chinese paintings, I usually forget to clean the palette, causing the paint to dry up. It is difficult to clean the corners of the palette. In response to this problem. The new design uses secondary injection molding. The inside is white soft rubber, 60% softness, which can be easily convex and cleaned. It is convenient and economical to use water. The edge provides support for transparent A B S and is not easy to deform. After cleaning the front, you can use the reverse side.

Morphological design evolution
There is a relationship between the edge of the shape and the grid form. Based on creativity, specific forms are needed to support creativity. In the Figure A series, the particularity of the body is emphasized, such as cute pandas, water droplets, flowers, etc., but the concept of convenient cleaning cannot be conveyed within a specific time. In the Figure B series, the size density of the lattice is evolved. In the C series, the possibility of body edge and creative communication, and the beauty of the edge are considered and pondered. Due to the roundness, it becomes hale and hearty, from more to less. The number of grids is generally 7 or 12 to cope with different colors. The most reasonable and balanced state is 7 grids. In the D and E and F series, the arrangement form of the grid is discussed, hoping that there will be a new fusion of this concept and form.
