HairArt Mannequin Head Lot of 8

Description

Found at an estate sale.
All used and exhibit signs of use view pictures.
Some of these have readable barcodes and some do not.
As to specifics like what model is this? and What type of hair is this? I probably can't answer that.
I brought these home and brushed them out for pictures no cleaning attempted on my end.
Most of these have the previous owners name written on them in the neck area.
The male head has some faint discoloration that might clean off with the proper cleaner.
One of the female heads has a hair pin stuck in the nose and one ear.
View all pictures the best judge of condition is you.
Thanks for looking!
