This is an easy-to-use fountain pen for everyday use. It's a used item with some scratches and stains, but there are no problems with the knock mechanism or writing feel, so it's recommended for those who want to try a knock-type fountain pen or those who want to use it heavily. [Note] There are no problems with the knock mechanism or writing, and the writing feel is good. I was using it until today. There is a small dent under the knock mechanism part. Also, there is rust? or paint peeling at the base of the clip. (Photos 4, 5, and 6) I have used and stored it with care, so it is generally clean, but it is a used item with scratches and stains, so please purchase it with your understanding. *Please check the dents and peeling in the photos. There is no cartridge cover or attached box. It will be sent with the "Tsukiyo" cartridge inserted. Two converters and three "Shinkai" cartridges will be included. Type of writing instrument... Fountain pen with 18k nib Pen function/material... Cartridge/converter compatible
