I was so excited to find this set of six Nuplaware, quart-sized containers “designed for freezer packaging”. “For home freezers, food lockers, refrigerators”, they are the “perfect food storage” containers! The set of six clear hard plastic containers hold one quart each and have red plastic “watertight seal lids” to “use again and again”. Nuplaware was produced by the New Plastic Corporation of Los Angeles, CA. The containers are in unused condition showing only stacking marks from being stored. The lids fit securely. There are a few tissue dividers included along with some cardboard instructions. The box is in excellent condition.
