Thank you for viewing. This is a set of 4 sharp pencil lead refills, mainly 0.7mm B, from KOKUYO, a well-known comprehensive writing instrument manufacturer. * Some UNI 0.7B sharp leads are also included. Since 2024, many items for mark sheets, mainly 1.3mm sharp pencils, have been released by various manufacturers, and I feel that thick-lead sharp pencils that can be written like pencils are taking over the market. However, I believe that many people still use 0.7mm leads, which were pioneers in this lead diameter. ☆Product Details★ ◎KOKUYO Sharp Lead Refill 0.7mm Black B (Blue Package) Contents: 30 leads Product number: PSR-B07-1P JAN code: 4901480364766 Retail price: 275 yen (tax included) ◎KOKUYO Sharp Lead Refill 0.7mm Black HB (Blue Package) Contents: 30 leads Product number: PSR-HB07-1P JAN code: 4901480364810 Retail price: 275 yen (tax included) Both are from: KOKUYO Co., Ltd. ◎UNI Sharp Lead Refill 0.7mm Black B (Off-white case) Contents: 40 leads Product number: Refill UL-S-0.7-40 B JAN code: 4902778274248 Retail price: 220 yen (tax included) / per piece Manufacturer: Mitsubishi Pencil Co., Ltd. ◆Current product ★Product Condition Brand new, unopened.
