This is a set of three desks and five chairs in HO Scale. Two of the desks are rolltops of different designs, and one is a standard desk. There are three swivel chairs with arms and two without.
They should be cleaned by soaking in acetone for 20 minutes, then fully rinsed, before painting. Some careful cleaning may be needed, similar to removal of flash from an injection molded item. Both acrylic and enamel paints should work, and I have used everything from $1 craft acrylics to expensive paints with success, at least to the limits of my mediocre painting ability. I have included the extra chairs as it is easy to damage them when removing the sprues due to the fine detail.
The photo of the painted model is of a prior design, and there may be minor differences from the model delivered.
The arrive unpainted and connected by sprues. They should be separated by carefully cutting the sprues with a quality cutter.
I test printed this model successfully in June 2013, and the unpainted photos show the current design.
