Dodge Chemical Co Feature Builder for Embalming 1940s to 1960s
The bottle is in perfect condition so far as I can see, but has shelf grime and dust.
There is a remaining cube of something in the bottle, which I presume to be leftover (and dried out) feature builder, but don't really know.
Please see photos for condition.
Shipping on Mondays. Payment must be received the previous day.
