Make sure you never run out of lead again by stocking up on mechanical pencil lead. As soon as your existing pencils reach the end of their lead sticks, you can easily replace them for non-stop writing. No matter what type of mechanical pencils you own, there are corresponding lead refills to fit them. Choose high-strength options if you tend to be heavy-handed while writing to resist breakage and extend the life of each refill.
Before making a purchasing decision, determine whether a mechanical pencil lead will fit your existing mechanical pencil. Some refills are made to work only with specific mechanical pencils but most feature semi-universal compatibility, fitting most 0.7 mm pencils or 0.5 mm pencils. Pay attention to the tip size of a mechanical pencil lead, which can range from a very thin 0.5 mm to a broad, thick 1.3 mm.
Because mechanical pencils don't use lead that's fused into the body, it's important to select lead refills that are made to resist breakage. Choose a high-polymer mechanical pencil lead, which is stronger than most conventional leads, or lead with integrated particles of nano-diamonds to make dark, bold imprints and crisp lines without breaking, smudging or fading.
For artistic uses, choose lead refills made of carbon, which work with drawing pencils and stand up to a high level of pressure and rigorous use while shading and sketching. If you prefer the smoothness of pens, but like the non-permanence of pencils, choose liquid pencil refills, which deliver a silky writing experience and can still be erased.
Due to the small, thin nature of a mechanical pencil lead, it's a good idea to choose an option that comes packaged in a handy storage container. A twist-top plastic dispenser keeps leads safe and neatly contained, plus allows easy dispensing. Leads that also come with replaceable erasers offer all-in-one solutions.
