I found this canister set while cleaning out a relative's house. It seems to have originally been a set of four, but I only have three: Flour, Sugar, and Coffee. The material is plastic. Although unused, it's over 50 years old and generally dusty with some stains. The outer box is severely deteriorated. The letters from the outside appear to have transferred to the inside. The lid knobs have bumps. This item has been stored for a long time. There are scratches, dust, stains, etc. due to storage. Please refrain from purchasing if you are sensitive to these issues. No returns accepted.
