This is the genuine waterproof case "EWC-80" specifically for the CASIO EXILIM EX-Z1000. It is compatible with depths up to 40m and can be used for diving and underwater photography. It has been used approximately 2-3 times and has been stored unused for over 15 years. Overall, it is in good condition, but there are some scratches in a few places (see images 10-12). Due to long-term storage, there is a possibility of aging, so we recommend preparing a new O-ring in particular. [Included Items] • Waterproof case body • Diffuser unit • Diffuser unit strap • Instruction manual • Outer box (*There are tears and stains) • O-ring (*Following the instruction manual, silicone grease was applied after shooting and stored in a plastic bag, but due to the possibility of aging, we recommend not using it and preparing a new one.
