Thank you for viewing! I am selling this because I purchased it but will be using a different lead. This is an authentic product with the Nonaka Boeki Co., Ltd. seal. Please note that I am not accepting price negotiations. Also, I will flatten the box and ship it in an envelope. - I will also send the Nonaka Boeki Co., Ltd. seal on the outer bag and the outer box (folded for shipping) as they are. - The flow pack (silver wrapping) will not be opened. If you have any questions, please ask in the comments section.
