Offering a set of 13 nostalgic pens, including the popular "color-changing ink" and "marble pens" of the time. These items have been stored at home for a long time. The ink flow and remaining amount vary for each pen. Operation has been confirmed ("ink came out"), but some may be difficult to use. Please understand that these are being sold as "junk/as-is" condition, as they may have low ink levels, deteriorated tips, color unevenness, etc. Recommended for collectors, interior decoration, or as a nostalgic item for those who loved them back then♡ I will perform a simple cleaning before shipping, but these are used/aged items. Please check the description and photos before purchasing. ◇Returns/cancellations are not accepted. ☆☆We are looking forward to those who can enjoy these nostalgic pens from the Showa to early Heisei eras☆☆
