Two of the three potential buyers have already bought it, so it looks like it won't sell this time, but I like it so I bought it again. A recording tape from around the 1960s.
The packaging design is great, so you can line them up or stack them wherever you like. While you can think of other uses for the contents, I think it would also be nice to use the case as a small item holder.
