This is the JAWS scuba mask & slate cleaner, a refillable spray cleaner built around concentrated pods. Drop a pod into the bottle, add tap water, and you have a full bottle of fresh, full-strength cleaner.
Use it to defog dive masks and clean slates on dive gear. When it runs low you reorder a small refill pod instead of a whole new bottle, so you reuse the same sprayer for years and keep plastic out of the landfill.
JAWS (Just Add Water Solutions) makes its concentrated refillable cleaners in the USA, built around a bottle-and-pod system that keeps plastic bottles out of the waste stream.
