Only one color is active at a time, keeping the other tips safely retracted and preventing accidental marks.\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 and general use.\u003c\/p\u003e\n\n\u003ch3\u003eQ: Is the plastic barrel durable enough for daily use?\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 suitable for important notes, planners, and documents.\u003c\/p\u003e\n\n\u003ch3\u003eQ: Is the pen refillable?\u003c\/h3\u003e\n\u003cp\u003eA: Yes. The ZENTO 3-Color is compatible with uni-ball ZENTO multi-color refill cartridges. You can replace individual ink colors as they run out, extending the life of the pen and reducing waste.\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 minimizes smearing, making the ZENTO 3-Color a practical and reliable choice for left-handed writers.\u003c\/p\u003e\n\n\u003ch3\u003eQ: How does this compare to the ZENTO Flow Model or ZENTO Signature?\u003c\/h3\u003e\n\u003cp\u003eA: The \u003cstrong\u003eZENTO 3-Color\u003c\/strong\u003e is the everyday value option — a full plastic barrel keeps it lightweight and affordable. The \u003cstrong\u003eZENTO Flow Model\u003c\/strong\u003e adds a metal grip zone for enhanced control, while the \u003cstrong\u003eZENTO Signature\u003c\/strong\u003e features a full metal barrel and magnetic snap cap for a premium writing experience.
