Before nylon and saran hair were available on the retail market "Jumbo Braid" hair was one of few choices for bulk doll hair. While this hair is intended to be used for extensions, it sometimes can be an inexpensive alternative for the not-so-picky customizer. Jumbo Braid is a type of kanekalon hair that can be identified by it's kinky texture. There are several rainbow colors available, the colors are the same no matter the brand. As well as a wide variety of browns, greys and black. Below are several pictures comparing the colors to My Little Ponies.
No additional information will be added to this guide as CustomPony recommends NYLON hair. However, this guide will stay up as it may be a good reference for someone :-)
