This mechanical pencil features a low center of gravity design for stable writing. Retail price: ¥2500 - Brand: ZEBRA - Model Name: Tect 2way RO - Lead Diameter: 0.5mm - Color: Black - Material: Plastic - Country of Manufacture: Japan Thank you for viewing. As stated in the second photo, I purchased this two days ago, but I don't think I'll have much opportunity to use it, so I'm putting it up for sale. I've only used it a few times for test writing, and it's in excellent condition, almost new. Immediate purchase is welcome. I'm also open to price negotiations! Please note that I have already disposed of the box, so it cannot be included.
