The Photography backdrops are designed for use with children, family or product photography. The backdrop patterns are seamless and printed with a fade-resistant ink for a vibrant long lasting colour. Ella Bella backdrops are made from 90gsm, acid free, recyclable paper. The roll is 1.22 x 3.65m (4ft x 12ft). The paper does not come on a cardboard core as our usual papers do, the opening is 2.5cm Diameter so the poles from our support system just about slides inside.
