رصاص أقلام رصاص ميكانيكية من ديلي (2B) قياس (0.5mm)

0.5mm leads produce fine, precise lines ideal for detailed notes and diagrams. 2B provides darker, smoother strokes compared with harder grades, making writing feel effortless and reducing the need to press hard.

1) Remove any paper or old lead from the pencil barrel. 2) Insert a new 0.5mm 2B lead into the feeder. 3) Gently push until it drops into place. 4) Click the pencil to feed more leads as needed. For best results, use a steady, light pressure to avoid breakage.

They’re great for exams, note-taking, drafting, and school or office work where you want dark, legible marks without heavy pressing. The 0.5mm size suits both writing and sketching tasks that require precision.

Use a light touch rather than pressing hard, avoid tapping the pencil against hard surfaces, and keep the pencil capped or stored properly. If you routinely experience breaks, consider using a slightly harder grade (e.g., HB) or a high-quality mechanical pencil that supports 0.5mm leads.

Yes. The leads are graphite-based and non-toxic for typical classroom use. They are designed for safe handling in standard school environments when used as intended with a mechanical pencil.

Yes. A 48-lead pack offers a bulk supply that reduces the need for frequent repurchases, making it cost-effective for daily writers, students, and remote workers who rely on reliable 0.5mm leads.

Durability depends on usage. For typical school or office writing, a 48-lead pack can last several weeks to a few months. Frequent sketching or heavy use will reduce the lifespan, while light note-taking will extend it.

2B offers a darker, softer line suitable for bold writing or shading, while HB is somewhat harder and produces a lighter line with less smudge. If you prefer darker text and smoother shading, the 2B lead in this pack is a good choice. See an alternative here: https://fepy.com/product/deli-0-5mm-lead-hb-24pc

Both provide dark, smooth lines, but feel and wear can vary by brand and pencil compatibility. Faber-Castell is another trusted option with similar specs. Compare here: https://fepy.com/product/faber-castell-0-5mm-lead-2b-24pc

In most cases, yes. The 0.5mm diameter is a standard size compatible with most 0.5mm mechanical pencils. If your pencil uses a unique feed mechanism, check the model’s compatibility notes or test with a single lead first.

Store leads in a cool, dry place away from moisture. Keep the pack sealed when not in use to prevent humidity from affecting lead quality. Avoid exposing leads to extreme heat or crushing the pack.
