When you rub the eraser tip over the ink, the friction generates heat that causes the pigment to become transparent — making it appear erased. The ink is not physically removed, so it may reappear if the paper is exposed to very cold temperatures.\u003c\/p\u003e\u003ch3\u003eQ: Can I erase on any type of paper?\u003c\/h3\u003e\u003cp\u003eA: Yes — the pens work on standard notebook paper, planner pages, and most office paper. For best results, use smooth paper with a consistent surface.\u003c\/p\u003e\u003ch3\u003eQ: Is the ink waterproof after writing?\u003c\/h3\u003e\u003cp\u003eA: The ink is water-resistant once dry, but it is not fully waterproof. Avoid prolonged exposure to moisture for important documents.\u003c\/p\u003e\u003ch3\u003eQ: How do I replace the refill?\u003c\/h3\u003e\u003cp\u003eA: Unscrew or pull apart the barrel (depending on the model), remove the empty cartridge, and insert the new refill. Make sure the tip is aligned before reassembling.\u003c\/p\u003e\u003ch3\u003eQ: Are these pens safe for children?\u003c\/h3\u003e\u003cp\u003eA: Yes — the ink is non-toxic and the pens are suitable for school-age children. Adult supervision is recommended for younger children.\u003c\/p\u003e\u003ch3\u003eQ: What colors are included in the set?\u003c\/h3\u003e\u003cp\u003eA: The set includes red (×1), blue (×1), and black (×2) pens, plus matching replacement refills for each color.\u003c\/p\u003e","brand":"TTpen","offers":[{"title":"Default Title","offer_id":55471761981745,"sku":"YX1243P4","price":12.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0804\/2630\/3793\/files\/O1CN013ojFuz1qdl2LogFVb__2212404915519-0-cib.jpg?v=1785147341","url":"https:\/\/www.ttpen.com\/products\/erasable-gel-pen-set-3-colors-0-5mm","provider":"TTpen","version":"1.0","type":"link"}
