The design is pinstriped directly onto an A4 frame. ※Not glass. Pinstriping is a traditional American art form where thin lines are hand-drawn freehand with a special brush. The paint used is 1 Shot Paint and RONAN. Felt is placed behind the design to make it stand out. The design is completely original. This is a one-of-a-kind piece. The paint may peel if rubbed with a hard object. This is a hobby-level artwork, so please refrain from purchasing if you are looking for perfection, as there may be slight imperfections such as blurring or misalignment in the design.
