Skip it if you want a weighted pencil: MUJI makes a separate [Low Center Gravity pencil](https://stationerytimes.com/guides/muji-low-center-gravity-mechanical-pencil/) for that. ![Three MUJI 0.5 mm mechanical pencils drawn to scale side by side by length](https://stationerytimes.com/images/muji-mechanical-pencils-lengths.svg?v=e47108af) *MUJI's three 0.5 mm mechanical pencils to scale: 13.5, 14.7 and 13.0 cm (1 mm = 4.4 px). Original illustration made for this guide. © Stationery Times.* ## Does the hexagonal shape stop it rolling? **MUJI USA says only that the hexagonal shape is easier to hold; it doesn't claim the pencil won't roll.** MUJI's [wooden hex pencil](https://stationerytimes.com/guides/muji-wooden-hexagonal-mechanical-pencil/) listing does say the shape prevents rolling. A six-sided barrel generally rolls less than a round one, but we haven't tested this pencil. ## How does it compare with MUJI's other mechanical pencils? **It's the lightest-looking of the three; the Low Center Gravity is longer and weighted, and the wooden hex is the shortest.** | | Aluminum | [Low Center Gravity](https://stationerytimes.com/guides/muji-low-center-gravity-mechanical-pencil/) | [Wooden Hex](https://stationerytimes.com/guides/muji-wooden-hexagonal-mechanical-pencil/) | |---|---|---|---| | Length | 13.5 cm | 14.7 cm | 13.0 cm | | Body | Aluminum | ABS resin, polypropylene, steel tip | Synthetic cedar | | Lead size | 0.5 mm | 0.5 mm | 0.5 mm | | Price band | $$ | $$ | $$ | Our [best mechanical pencils](https://stationerytimes.com/guides/best-mechanical-pencils/) roundup compares other makers. ## What do you need to buy with it? **Lead: MUJI USA says refills are sold separately, and sells 0.5 mm lead in its own listing.** The pencil's listing doesn't say a lead is included, unlike the [wooden hex pencil](https://stationerytimes.com/guides/muji-wooden-hexagonal-mechanical-pencil/), which comes with 0.5 HB. Our [best mechanical pencil lead](https://stationerytimes.com/guides/best-mechanical-pencil-lead/) guide explains grades. MUJI USA also sells an aluminum hexagonal ballpoint pen, 0.7 mm, in the same shape. Both are metal, and MUJI USA's care note for the pencil warns that the tip is sharp: take care not to injure yourself or damage it by dropping it. ## Where is it made, and what does it cost? **In Japan: MUJI USA gives Japan as the country or region of origin.** The pencil is in our $$ band ($5–20).
