Balsam Hill's award-winning True Needle technology is the secret behind the stunning realism of our most realistic artificial Christmas trees. Each lush tree branch is carefully constructed from injection-molded PE, which is then dyed with various pigments to recreate the stunning color, texture, and structure of real evergreen needles. A unique feature of our best artificial Christmas trees is the color variation in the branches. If you look closely, you...ll notice that the branch is as brown as nature intended, while the needles have a beautiful green gradient.
