We presently produce 3 types of vines (resin, vinyl, and urethane), as well as 3 different styles for the vinyl vines (smooth, rough, and hairy).
The resin vines are the most indestructible, good for Orangutans. Mandrills and the other destructive species.
The urethane vines are good for Gibbons, Siamangs, etc. They
also can be used as insulators for hot wire.
The vinyl vines are excellent for the smaller species and are the betterlooking of all of the vines.
