Press the tab for the colour you want; the nib extends and locks. Press another tab to switch. The mechanism is smooth, positive, and satisfying - a significant improvement over the push-button selectors found on most multi-colour pens. The selected colour is always visible at a glance from the side of the pen.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e0.38mm and 0.5mm Nib Options - Precise, Consistent Line Width:\u003c\/strong\u003e The uni-ball one 3 is available in two nib sizes - 0.38mm for fine, precise writing, note-taking, and annotation; and 0.5mm for a slightly bolder, more expressive line. Both sizes deliver the consistent, skip-free performance that uni-ball is known for. The 0.38mm is particularly popular for journaling, bullet journaling, and writing in small notebooks; the 0.5mm for everyday writing, to-do lists, and general use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact Mini Body - Clip to Your Notebook, Carry Everywhere:\u003c\/strong\u003e The uni-ball one 3 is designed in a compact, slightly shorter-than-standard body - slim enough to clip to the cover of an A5 or B5 notebook without adding bulk, light enough to forget it is there. The metal clip is sturdy and spring-loaded, gripping securely to notebook covers, shirt pockets, and bag straps. The pen body is available in a curated range of muted, sophisticated colours - Matte Black, White, Shirt Blue, Mocha Brown, Orange Red, and Teal - each finished in a smooth matte lacquer that feels premium in the hand.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eJapanese Import - Original uni-ball Packaging:\u003c\/strong\u003e The uni-ball one 3 is imported directly from Japan in original Mitsubishi Pencil retail packaging - the distinctive uni-ball one 3 branded sleeve with colour and nib size clearly marked.
