"chair"— pen contain / pen contain

Its design inspiration is from armchair.
Uneven chair armrest makes different pens lean against. And its openings allow users easily to get different kinds of pens they expect.
Use the grid to replace the traditional pen container bottom. Even if the nib of the pen is places down into the brush pot, it will not be damaged. The brush pot allows users to put pen as one likes, without considering whether the pen’s nib is up and down. In addition, you don’t have to worry if the pen will draw to your hand. What’s more, the pen also can keep the bottom clean.
