Cleaned with disinfectant wipes. Stored for a long period without use. Due to storage, the non-woven fabric on the back has peeled off, so I have removed it all. There is also some dirt on the sponge, but there are no issues with the operation. As this is a used item, please understand that no returns or refunds are accepted. I will use recycled packaging materials, but I will pack it securely and ship it promptly! I am also listing this on other flea market apps, so I may suddenly remove the listing. - Brand: Smart - Model Name: WONDER Core - Model Number: WCS-612-JCN4 - Color: Blue - Features: Exercise machine
