Superior thermo-sensitive ink and a soft rubber grip make the pens write smoothly! Great pens for coloring, kids' doodling, scrapbooking, sketching, drawing, doodling, writing, and getting creative in a fun and skilled way. Please avoid direct sun exposure and ensure that you remove the wax completely from the nib before first use. Retract the tip after use to prevent it from drying out. If the pen does not work, try scribbling on paper for a few seconds to make the ink run again. Also it can be printed your own logo.
