4' x 100' 7mil on Black Mylar

Now, light that would have "lost" is used as efficiently as possible. With a black PE film backing, 7 mil thick mylar is stronger. Unlike other mylars, this product will not tear easily. To achieve maximum light homogeneity, attach to any surface. Be inventive and attach to pots, buildings, or poles. Highly introspective. Apply on either side. Unlike any other variety available, it is twice as thick.
