Science and Handmade Toys for Parents and Children to Enjoy Together Let's Play with Katcha-kun vol. 2 Supervised by: Masaki Kurokawa Published by: Patchwork Tsushinsha Release Date: 2006/11/1 Price: 1,200 yen (excluding tax) New and unused, but it has been several years since purchase, so I have marked it as "Like New." It does not have the luster it had immediately after purchase. There is a slight crease on the lower left corner of the back cover, which is not very noticeable (see photo 2).
