I bought it to erase the prices from the tags on clothes in case of a gift. It erases them perfectly and nothing is visible.

Very good markers only for street tagging because for sketching in a notebook they are useless. At first, the paper gets wet and it also smudges, and this is because they are acrylic water-based markers and the ink contains water. Many times, because they are pump-action and you press the tip to get ink, it causes oversaturation when you press the tip. I really regret buying them because I have around 20 markers and at a price of 2.50 euros each, it is truly unacceptable. For such a price, it is better to buy MTN 94' Calligraphy markers for 2.80 euros, which are alcohol-based and not pump-action, but gravity-feed with the classic sponge that feeds the tip.
