{"product_id":"uni-pro-mechanical-pencil-m3-552-0-3-mm","title":"Uni Pro Mechanical Pencil M3-552, 0.3 mm","description":"The uni Pro M3-552 carries a 0.3 mm lead, the thinnest size used for genuinely fine technical work — architectural detail, cartography, or any layout where a slightly thicker line would blur small marks together. The barrel sits low in the hand thanks to a knurled steel grip section positioned to reduce fatigue over long drafting sessions, and a fixed 4.0 mm steel needle sleeve keeps the lead protected and visible when tracking along a ruler, stencil, or template.\u003cbr\u003e\u003cbr\u003eA twist-adjustable window near the top lets you manually set which lead grade is loaded, from 2B through 2H, so you can keep track of hardness without guessing — useful if you swap grades for different parts of a drawing. A refillable eraser sits under the push-cap for quick corrections.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003cul\u003e\n\u003cli\u003eLead size: 0.3 mm\u003c\/li\u003e\n\u003cli\u003eTip: fixed 4.0 mm steel guide sleeve\u003c\/li\u003e\n\u003cli\u003eGrip: knurled steel, low center of gravity\u003c\/li\u003e\n\u003cli\u003eFeatures: adjustable lead grade indicator, refillable top eraser\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Uni Mitsubishi","offers":[{"title":"Default Title","offer_id":51785619997021,"sku":"4902778364260","price":2300.0,"currency_code":"JPY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0873\/4405\/4621\/files\/uni-pro-mechanical-pencil-m3-552-0.3-mm_4902778364260.jpg?v=1718414651","url":"https:\/\/unfide.com\/sv\/products\/uni-pro-mechanical-pencil-m3-552-0-3-mm","provider":"UNFADE","version":"1.0","type":"link"}
