{"product_id":"zebra-pens-delguard-mechanical-pencil-refills","title":"DelGuard Mechanical Pencil Refills","description":"\u003cp\u003eZebra engineers DelGuard leads to match the pencil's dual-spring protection system, creating a refill specifically designed to work with the mechanism rather than against it. Standard leads often break in DelGuard pencils because they weren't formulated for the unique pressure distribution of the spring system. These specialized refills maintain consistent hardness throughout each 60mm length, eliminating the weak spots that cause conventional leads to snap under the pencil's protective grip.\u003c\/p\u003e\n\u003cp\u003eThe polymer-graphite blend delivers smooth, even laydown while resisting the kind of sudden fractures that interrupt detailed work. Whether you press hard through technical drawings or maintain light touch for sketching, the lead flexes slightly within the spring mechanism rather than shattering. This engineered compatibility means you spend more time actually drawing and less time advancing fresh lead.\u003c\/p\u003e\n\u003cp\u003eEach tube contains multiple leads in your preferred grade, 2B for bold sketching, HB for general writing, or harder grades for precision drafting. Keep extras on hand; the DelGuard system works brilliantly, but only when paired with leads built to complement its engineering.\u003c\/p\u003e","brand":"Zebra Pens","offers":[{"title":"0.5 mm \/ 12 pieces","offer_id":47973625692389,"sku":"52967","price":1.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0726\/6890\/5701\/files\/s52967.jpg?v=1761684592","url":"https:\/\/www.texasart.mom\/products\/zebra-pens-delguard-mechanical-pencil-refills","provider":"Texas Art Supply","version":"1.0","type":"link"}
