The Q-Connect 0.7mm HB lead refills are designed for students, artists, and professionals who rely on mechanical pencils for consistent writing and sketching. These high-polymer leads offer a perfect balance of durability and line darkness, though they are specifically sized for 0.7mm mechanisms and will not fit thinner 0.5mm barrels. This bulk pack is an excellent value for heavy users, ensuring you have a long-lasting supply of 144 leads across 12 convenient storage tubes.

No, these are 0.7mm leads and will be too thick to fit into a 0.5mm pencil mechanism.
Yes, as standard HB graphite, these marks are easily removed with a standard eraser.
HB indicates 'Hard Black', representing the middle ground on the graphite scale between hard and soft.
The pack includes 12 individual plastic tubes.
Yes, the 0.7mm size is often preferred for technical sketching where a slightly bolder, more durable line is required.
No, modern pencil lead is made from a mixture of graphite and clay; it contains no actual lead.
Ensure you are not extending more than 1-2mm of lead at a time. Using too much lead leverage makes it prone to snapping.
Check the nib for a stuck piece of broken graphite. You can gently clear the path using a thin needle or by cycling the click mechanism.
To use these refills, simply remove the cap from your 0.7mm mechanical pencil and insert 2 to 3 leads into the storage chamber. Do not overfill the chamber, as this can cause the lead-advancement mechanism to jam. When handling the leads, try to hold them by the ends to avoid transferring skin oils to the graphite, which can affect writing smoothness. Store the remaining tubes in a dry, cool place to prevent moisture from affecting the polymer composition. If you feel resistance when inserting the lead, check that no broken fragments remain inside the pencil's nib from a previous lead snap.
