FriXion Gel Erasable Pen - black ink
FriXion Ball Erasable Gel Pen contains a thermo-sensitive gel ink formula which disappears with erasing friction or the hear of an iron! .7mm point with smooth writing gel ink. Black ink.
This is the pen that I love to use for tracing onto lighter backgrounds for embroidery projects. I especially love it because when the stitching is complete - the tracing lines disappear when the stitching is pressed. (Especially wonderful when using light colored flosses!)
