Cast in translucent red acrylic with polished silver trim, the cap is finished with a Japanese-designed illustration of a very contented cat — wine glass in one paw, bottle in the other — raising a toast to good writing. It's a small pen with a big personality, and one of the few fountain pens genuinely small enough to disappear into a jacket pocket or pencil case.\u003c\/p\u003e\n\u003ch4 dir=\"ltr\" class=\"mt-2 -mb-1 text-base font-bold\"\u003eDesign \u0026amp; Construction\u003c\/h4\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe Mini Pocket's proportions are built for portability first. Capped, the pen measures approximately 117.3 mm; the body alone is approximately 107.7 mm, with the cap adding approximately 49.5 mm when posted. Body diameter is approximately 14.5 mm, with a grip diameter of approximately 11.7 mm — slim enough for a genuinely pocketable pen, while still comfortable for note-taking and journaling sessions. Weight is approximately 24 g. The cap is screw-on, with a polished chrome clip.\u003c\/p\u003e\n\u003ch4 dir=\"ltr\" class=\"mt-2 -mb-1 text-base font-bold\"\u003eEyedropper Filling System \u0026amp; Shut-Off Valve\u003c\/h4\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eDespite its small size, the Mini Pocket holds a genuinely generous 1.5 ml of ink through a Japanese-style eyedropper system with an integrated shut-off valve. To fill, unscrew the grip section, use the included glass eyedropper to draw ink, deposit it into the barrel, and reassemble. Before writing, unscrew the blind cap at the end of the barrel to release the internal valve and open ink flow to the nib; screw it closed again for travel, and the valve seals the reservoir against leaks — reassuring for a pen that's meant to live in a bag or a pocket.\u003c\/p\u003e\n\u003ch4 dir=\"ltr\" class=\"mt-2 -mb-1 text-base font-bold\"\u003eNib Options\u003c\/h4\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe Cheer Kitty is fitted with a #5 JoWo stainless steel nib, available at Shosai in:\u003c\/p\u003e\n\u003cul dir=\"ltr\" 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 print:block print:space-y-1\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eExtra Fine (EF)\u003c\/strong\u003e — a precise, controlled line for small handwriting\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eFine (F)\u003c\/strong\u003e — the most versatile everyday width\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eMedium (M)\u003c\/strong\u003e — broader and wetter, good for shading inks\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eBroad (B)\u003c\/strong\u003e — a bold, generous line\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cmeta charset=\"utf-8\"\u003e \u003cstrong\u003e1.4 mm Stub\u003c\/strong\u003e — an italic-style grind that adds crisp line variation to every stroke\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eOpus 88 nibs tend to write slightly broader than equivalent Japanese sizes — if you usually reach for a Pilot or Sailor fine, consider sizing down one step.\u003c\/p\u003e\n\u003ch4 dir=\"ltr\" class=\"mt-2 -mb-1 text-base font-bold\"\u003eLifetime Replacement Guarantee\u003c\/h4\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eEvery Opus 88 fountain pen sold at Shosai is backed by a lifetime replacement guarantee.
