Thank you for viewing. This is a listing for five packs of Mitsubishi Uni (UNI) Nano Dia 0.9mm HB mechanical pencil lead. This is my third listing, following ones in March and November of last year. Nano Dia lead was the first mechanical pencil lead in the world to incorporate "nano-diamonds," and it gained popularity for its improved strength and smoothness compared to previous products. 0.9mm lead can be used in a variety of mechanical pencils, such as the Mitsubishi Shift 0.9, Kokuyo Pencil Sharp 0.9, Pentel Tough Sharp 0.9, and the Graphgear series 0.9, with a wide selection similar to 0.5mm. Its uses range from marking answer sheets to marking work for construction and civil engineering professionals, widely used as a substitute for pencils! How about it for those who often use 0.9mm mechanical pencils? The current UNI mechanical pencil lead (white-based package) also carries on the 0.9HB, and its ease of use suggests high demand and popularity. ☆Product Details Nano Dia 0.9mm Black Lead HB (Blue Case) Contents: 36 leads per pack Product Number: Uni 0.9-202D HB JAN Code: 4902778030363 Retail Price: 220 yen (tax included) / per piece Shipped from: Mitsubishi Pencil Co., Ltd. ◆Discontinued in December 2021 ★Product Condition Brand new, unopened.
