Please consult with me on price negotiations for two or more items. I do not offer individual sales or changes to combinations. It is recommended to contact me with a comment before purchasing to confirm stock. Please only purchase if you understand that I am a private seller and will be doing a personal inspection. Items will be simply packaged. The four bonus pens may have been used for testing, etc. Please consider them as a bonus. These items were purchased in stores and stored at home. Please only purchase if you understand.
