Shiga Insect Large German Box 2-Box Set

I bought these in bulk with my last bonus about 26 years ago when I was single. I thought I'd finally be able to collect insects after raising my children and settling into my career, but presbyopia made it difficult to prepare specimens, so the specimen boxes I had bought became unnecessary.
I have 7 boxes remaining that are completely unused and have been kept in their original cardboard boxes. I believe they were originally priced at ￥8,000 per box. Therefore, I am offering two boxes for ￥19,000, including fees and shipping. The dimensions are 51cm x 42cm x 6cm.
I also have many unused pinning boards in various sizes and pinned needles in various sizes. I will be listing them sequentially.

Thank you for looking.
