(Black Crisp and Namae Pen that is hard to fall off even when rubbed off)
The newly developed oil-based pigment ink allows you to write on clear materials such as plastic bags and plastic materials, and it wont come off even if rubbed.
You can write on glass and other craft tapes that were difficult to write with traditional permanent markers. It also prevents bleeding even when writing on the fabric and does not fall off even when washed.
The Smudge Prevention Pen for Cloth Writing (sold separately) can significantly reduce smearing.
