I found this while cleaning out an old stationery store. It's quite old, but unused and in very good condition, I think. I'm not familiar with the materials used for seals, so I'm not sure what it's made of. However, since it's from about 50 years ago, I believe the material is of good quality. The case is falling apart, so if you don't need it, I'll ship only the contents! Condition: Used, but unused. Please understand that this item has been stored for a long time before purchasing. Please check the images for the condition. There may be some minor scratches that I have overlooked. Please purchase only if you are not concerned about this and can understand. I will perform a simple cleaning with disinfectant wipes and pack and ship the item to prevent damage as much as possible. *Please refrain from purchasing if you are a perfectionist, if you are looking for a perfect item, or if you are overly concerned about the condition. I have included as many images as possible, so please take a look and confirm the details.
