A fun set of glitter pastel colored pigment pens that work beautifully on white and black papers. Ink is also erasable which will erase the ink but may leave some glitter behind. Ink appears to erase cleanly from the page due to the heat produced from the friction of the rubbing of the eraser. Ink is thermo responsive/sensitive and it is highly recommended not to leave anything written in this ink in a heated environment (i.e. hot car). Also not recommended to be used on papers that may come into contact with heat during processing such as (but not limited to) mailings, cheques, etc. Erased ink can also reappear in -10C degrees.
