PRS Hanko Oakwood Premium Edition - Brand: PRS (Paul Reed Smith) - Item Type: Hanko (Personal Seal) - Material: Oakwood - Special Edition: Premium Edition Thank you for viewing. This is a hanko made from oak wood aged for 100+ years and then matured for 50 years. The tip is marked with Arita. Please contact Mitsubishi Pencil Co., Ltd. to inquire about replacement. I received this from PRS about a decade ago when I purchased a PRS guitar that cost around 700,000 yen. I believe this is no longer available, so please consider this opportunity.
