We use these markers to a misuse: temporary tattoos on the skin! Thanks to its composition, the product does not cause any allergy on the skin. The choice and quality of colors used to make stunning designs. The longevity of these markers is remarkable: they do not dry out and the tip is filled on request by pressing it. A purchase at an affordable price because the unit cost in the shops is exorbitant! I highly recommend this product, but only if you are not in a hurry: they come from far away!
