The magic sits entirely in the chemical formulation of the ink: the carbon pigment particles chemically bind to paper fibers, rendering the lines completely immune to water, alcohol markers, and erasing forces. This makes them the ultimate layout tool to establish your linework before overlaying liquid media or heavy graphite under-sketching.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eChoosing the right width\u003c\/strong\u003e\u003cbr\u003eThree widths serve different roles. The 0.1mm is for highly detailed cross-hatching, architectural linework, and any area where a 0.3mm would be too heavy. The 0.1mm tip is fragile and should not be pressed on rough paper surfaces. The 0.3mm is the most versatile — fine enough for most detailed work and robust enough for regular daily use. The 0.5mm is for outlines, thicker marks, and panels where a more confident, broader line is appropriate. Most illustrators use two widths — 0.3mm for detail and 0.5mm for outlines.\u003cbr\u003e\u003c\/p\u003e","brand":"Mitsubishi Uni","offers":[{"title":"Default Title","offer_id":53246168400200,"sku":null,"price":0.0,"currency_code":"GBP","in_stock":false}],"url":"https:\/\/inkwellartsupplies.com\/products\/uni-pin-fine-line-drawing-pens","provider":"Inkwell Art Supplies","version":"1.0","type":"link"}
