This Gelly Roll Gel Pen set from Sakura includes 3 white gel pens with different line widths in a blister pack. The Japanese brand Sakura is considered the inventor of the gel pen. These pens contain gel-based ink, allowing for a very smooth writing experience. Thanks to the transparent material, you can see how much ink is left in the pen. You can use the gel pen until the ink is completely used up. The gel pens have high opacity, are lightfast, waterproof, do not fade, and can be used on colored, white, black, matte, and glossy paper. This set includes the following line widths: 05 fine (0.3 mm), 08 medium (0.4 mm), and 10 broad (0.5 mm). Gel pens are excellent for drawing, decorating, and writing. Just think of hand lettering, card making, bullet journaling, Zentangle, and illustrating. The Sakura Gelly Roll pens are available both in sets and individually in various colors and with different effects such as glitter and metallic or in fluorescent shades.
