This two tier hanging basket is made with annealed steel wire. The top basket is 8 1/2 inches round by 3 inches deep and the top basket is 7 inches round by 2 1/4 inches deep. These are made by twisting multiple strands of wire together.This basket does not sit perfectly level and is rustic in style.It is a handmade basket, perfectly imperfect. This basket should by protected from wet and damp to prevent rust. I also recommend cleaning and conditioning with cooking oil every few months or if it needs cleaning.Just wipe with a cloth wet with cooking oil followed by a clean dry cloth.All my baskets are done this way before shipping.
