Hydro Foams High performance hydrofoam pads for GSW's Wet Palette. High thickness hydrophilic foam for increased fluid retention, whilst preventing wrinkles when drying out. Treated by Sanitized® to prevent mould and impurities, ensuring their longevity and capability to be reused. This treatment is not infinite, so it will lose effectiveness against fungi with time, water changes, and high temperatures. There is no minimum or maximum date from which the fungi will be generated, but good conservation will extend its effectiveness for many months. Size: 125x175mm Contains: 2 Sanitized® treated sponges in color white
