It works directly on the foil surface with controlled heat bursts, through a protective silicone or vinyl sheet.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eAnatomy of a holo card — why heat works:\u003c\/strong\u003e\u003cbr\u003e\nA Pokémon holo is a system of layers: clear plastic film → metallic foil → cardstock → black core → back. The crease \"goes through\" all layers. The heat burst applied through the protective sheet warms and temporarily makes the top plastic film malleable — allowing the crease to be reduced with controlled pressure, before it cools and becomes rigid again. It does not work on the inner cardstock — for that, humidification is needed.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCorrect usage — BLU mode only:\u003c\/strong\u003e\u003cbr\u003e\nDouble click → RED light (high temperature — do not use on cards). Double click again → BLUE light (low temperature). Use exclusively with BLUE light active. 3-second bursts, no more — the tip overheats if held down. Always work with the protective sheet (silicone or vinyl) between the pen and the card. Move parallel to the crease, from the inside towards the edge. Integrated auto-shutoff, thermal protection if overheating is detected.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eThe ideal session:\u003c\/strong\u003e pre-humidification with HUMIDITY STORM™ (2–8 hours) → thermal pen on the still flexible card → final pressing for 2–3 days with clamps concentrated on the crease.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003e⚠️ Reverse holo: utmost caution.\u003c\/strong\u003e The foil in reverse is a single layer without a protective film on top — it discolors easily. Always use vinyl (not silicone), very short bursts, test on inexpensive reverse holos first.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e⚠️ Always practice on inexpensive cards of the same type before proceeding with valuable cards.\u003c\/strong\u003e\u003c\/p\u003e","brand":"Spark \u0026 Polish®","offers":[{"title":"Default Title","offer_id":57114597392719,"sku":"SP-ACC-TPEN","price":37.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1002\/3138\/1327\/files\/hero_12.jpg?v=1779967071","url":"https:\/\/checkout.sparkandpolish.com\/en\/products\/penna-termica-edge-corner-repair","provider":"Spark \u0026 Polish","version":"1.0","type":"link"}
