The moment the gel ink touches paper, it flows without skipping, without blobbing, without effort. The 0.5mm tip is fine enough for small handwriting but bold enough to read at a glance. Click it open, write, click it closed — a ritual so smooth it becomes second nature. Three colors, one set, every writing task covered.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eBrand: uni-ball (Mitsubishi Pencil)\u003c\/li\u003e\n\u003cli\u003eModel: Signo RT UMN-155\u003c\/li\u003e\n\u003cli\u003eOrigin: Japan\u003c\/li\u003e\n\u003cli\u003eTip Size: 0.5mm\u003c\/li\u003e\n\u003cli\u003eInk Type: Signo gel ink — quick-dry, smear-resistant\u003c\/li\u003e\n\u003cli\u003eMechanism: Retractable click\u003c\/li\u003e\n\u003cli\u003eInk Colors: Black, Blue, Red\u003c\/li\u003e\n\u003cli\u003ePack Quantity: 3 pens\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003ePerfect For\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eStudents — class notes, exams, and assignments\u003c\/li\u003e\n\u003cli\u003eOffice \u0026amp; professional use — documents, signatures, annotations\u003c\/li\u003e\n\u003cli\u003eColor-coded note-taking \u0026amp; study systems\u003c\/li\u003e\n\u003cli\u003eJournaling \u0026amp; planner writing\u003c\/li\u003e\n\u003cli\u003eGifting — a classic Japanese pen set for any writer\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"uni-ball","offers":[{"title":"3 Black","offer_id":54340745822513,"sku":"UMN-155-3C-1","price":12.0,"currency_code":"USD","in_stock":true},{"title":"3 Red","offer_id":54340745855281,"sku":"UMN-155-3C-2","price":12.0,"currency_code":"USD","in_stock":true},{"title":"3 Blue","offer_id":54340745888049,"sku":"UMN-155-3C-3","price":12.0,"currency_code":"USD","in_stock":true},{"title":"3 Mixed","offer_id":54340745920817,"sku":"UMN-155-3C-4","price":12.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0804\/2630\/3793\/files\/O1CN01oZRiOb1ogO3RT3UOu__743905254.jpg_503ddea2-ce40-45bd-bc34-6b58b19ba2f7.webp?v=1779856623","url":"https:\/\/www.ttpen.com\/products\/uni-ball-signo-rt-umn-155-retractable-gel-pen-0-5mm-3-pack-black-blue-red","provider":"TTpen","version":"1.0","type":"link"}
