Frequently Asked Questions

Q: What sizes of mechanical pencil lead refills are included in this set?

A: This set of HB mechanical pencil lead refills is available in four tip sizes: 0.3mm, 0.5mm, 0.7mm, and 0.9mm. Each size is sold as a 5-piece set, so you can choose the width that suits your drawing, writing, or sketching needs.

Q: Are these HB lead refills compatible with all mechanical pencils?

A: Yes — these standard HB automatic pencil lead refills are designed to fit most mechanical pencils that accept 0.3mm, 0.5mm, 0.7mm, or 0.9mm leads. They work great for student pencils, professional drafting tools, and everyday writing pens.

Q: What is HB lead hardness, and is it good for everyday use?

A: HB is the universal mid-range lead hardness — it sits right in the middle of the hardness scale, making it ideal for everyday writing, sketching, and technical drawing. It produces dark, clear lines without being too soft (which smudges easily) or too hard (which can scratch paper or leave faint marks).

Q: How long are the individual lead refills?

A: Each individual lead refill measures 60mm in length, providing a generous amount of usable lead before you need to reload your mechanical pencil.
