This is a 5-piece set of Joseph Joseph NEST LOCK containers (color: SKY). Of these, only the 1.85L size has been used once, so the item condition is listed as "Like New." There is no lingering odor. The other four containers are completely unused and have been stored in the box with the bags still on, as shown in the third photo. JOSEPH JOSEPH JOSEPH NEST LOCK SKY Nest Lock Set
