Special Chemical Signs is what is written in cursive handwriting within this box. Marked E-104 on the outside, this mysterious Chemist Box is hinged and opens up to four compartments. A beautiful aged wood, this box might have once sat in an unknown chemist's laboratory. Measuring 5" x 5.5", it looks as though its top was once repaired by glue, possibly by the chemist himself? Who knows, but this little box is curious and really cool.
