{"product_id":"uni-ball-one-f-gel-pen","title":"Uni-ball ONE F Gel Pen","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eOne of the better everyday gel pens going, and one of the more popular ones in the Japanese stationery community for good reason. The One F's ink uses large pigment particles that sit on the surface of the paper rather than absorbing into it — which means the black comes out genuinely dark and crisp, not washed out or grey. Fast-drying, fade-resistant and water-resistant.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe barrel is wider than a standard pen with a lower centre of gravity, which gives it a surprisingly balanced, comfortable feel in the hand — particularly over long writing sessions. The spring-loaded metal clip is distinctive without being showy, and the retractable nib means no cap to lose. \u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eChoose your barrel colour and tip size above: 0.38mm for fine, precise lines; 0.5mm for a slightly smoother, broader stroke.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eAlso by Uni-ball: the \u003ca class=\"underline underline underline-offset-2 decoration-1 decoration-current\/40 hover:decoration-current focus:decoration-current\" href=\"#\"\u003eOne P\u003c\/a\u003e — a shorter, chunkier version with the same ink and the same clip, ideal if you prefer a compact pen.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eBy Uni Mitsubishi, made in Japan.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eInk: Black pigment gel, water-resistant, fade-resistant\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eTip sizes: 0.38mm or 0.5mm\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eTip: Retractable metal\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eClip: Spring-loaded metal\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eLength: 14cm\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eGrip diameter: approx. 1cm\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eRefillable: Yes (UMR-38S \/ UMR-5S refills)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Uni-ball","offers":[{"title":"Faded Blue 0.5mm","offer_id":57755847786844,"sku":"UNB-9922-ONEF-BLU","price":4.0,"currency_code":"GBP","in_stock":true},{"title":"Faded Green 0.5mm","offer_id":57755847852380,"sku":"UNB-9939-ONEF-GRN","price":4.0,"currency_code":"GBP","in_stock":true},{"title":"Cocoa Brown 0.5mm","offer_id":57755848048988,"sku":"UNB-0518-COCOABRN-05","price":4.0,"currency_code":"GBP","in_stock":true},{"title":"Pale Green 0.5mm","offer_id":57755848114524,"sku":"UNB-0464-PALE-GRN-05","price":4.0,"currency_code":"GBP","in_stock":true},{"title":"Black 0.38mm","offer_id":57755848180060,"sku":"UNB-9953-ONEF-BLK","price":4.0,"currency_code":"GBP","in_stock":true},{"title":"Faded Seafog 0.38mm","offer_id":57755847917916,"sku":"UNB-1092-SEAFOG","price":4.0,"currency_code":"GBP","in_stock":true},{"title":"Faded Pink 0.38mm","offer_id":57755847983452,"sku":"UNB-9908-ONEF-PNK","price":4.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0952\/7040\/4444\/files\/uniball-one-gel-pen-six-colour-collection-flatlay.webp?v=1780094030","url":"https:\/\/www.stcshop.co.uk\/products\/uni-ball-one-f-gel-pen","provider":"Subject to Change","version":"1.0","type":"link"}
