Only one color is active at a time, keeping the other tips safely retracted.\u003c\/p\u003e\n\n\u003ch3\u003eQ: What is the difference between the 0.38mm and 0.5mm variants?\u003c\/h3\u003e\n\u003cp\u003eA: The \u003cstrong\u003e0.38mm\u003c\/strong\u003e produces an extra-fine line, ideal for small handwriting, dense note-taking, and detailed annotations. The \u003cstrong\u003e0.5mm\u003c\/strong\u003e offers a slightly broader, smoother stroke — the most popular all-purpose size for everyday writing.\u003c\/p\u003e\n\n\u003ch3\u003eQ: Why does this pen have a metal grip on a plastic barrel?\u003c\/h3\u003e\n\u003cp\u003eA: The combination is intentional. The \u003cstrong\u003eplastic barrel\u003c\/strong\u003e keeps the pen lightweight for all-day carry, while the \u003cstrong\u003emetal grip zone\u003c\/strong\u003e adds tactile control and prevents slipping during long writing sessions — the best of both materials.\u003c\/p\u003e\n\n\u003ch3\u003eQ: Is the ink waterproof or fade-resistant?\u003c\/h3\u003e\n\u003cp\u003eA: Yes. All three ink colors use water-based gel ink that is highly water-resistant and formulated to resist fading over time, making this pen reliable for important notes, records, and documents.\u003c\/p\u003e\n\n\u003ch3\u003eQ: Is the pen refillable?\u003c\/h3\u003e\n\u003cp\u003eA: Yes. The ZENTO Flow Model is compatible with uni-ball ZENTO multi-color refill cartridges. Replace individual ink colors as they run out without replacing the entire pen.\u003c\/p\u003e\n\n\u003ch3\u003eQ: Is this pen suitable for left-handed writers?\u003c\/h3\u003e\n\u003cp\u003eA: Absolutely. The quick-drying gel ink across all three colors significantly reduces smearing, making the ZENTO Flow Model a practical choice for left-handed writers.\u003c\/p\u003e\n\n\u003ch3\u003eQ: What paper types work best with this pen?\u003c\/h3\u003e\n\u003cp\u003eA: The ZENTO Flow Model performs well on smooth and standard office paper. For best results with the 0.38mm tip, use coated or semi-coated paper (e.g., Rhodia, Clairefontaine). The 0.5mm tip handles a wider range of paper textures with ease.\u003c\/p\u003e","brand":"Mitsubishi Pencil (uni)","offers":[{"title":"Beige 0.5mm","offer_id":55820116754737,"sku":"UB-ZENTO-F3C-1","price":39.0,"currency_code":"USD","in_stock":true},{"title":"Wine 0.5mm","offer_id":55820116787505,"sku":"UB-ZENTO-F3C-2","price":39.0,"currency_code":"USD","in_stock":true},{"title":"Green 0.38mm","offer_id":55820116820273,"sku":"UB-ZENTO-F3C-3","price":39.0,"currency_code":"USD","in_stock":true},{"title":"Navy 0.38mm","offer_id":55820116853041,"sku":"UB-ZENTO-F3C-4","price":39.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0804\/2630\/3793\/files\/O1CN01k46bSd21pAgahb4Yl__42307033.jpg_73169020-1193-4d00-9bb2-2ccc07eb56fa.webp?v=1787213529","url":"https:\/\/www.ttpen.com\/products\/uni-ball-zento-flow-model-3-color-gel-pen","provider":"TTpen","version":"1.0","type":"link"}
