This product can keep acrylic/water-based paints moist and ready for use for a long time. So, you don’t have to worry that the paints will dry out. The highly efficient sponge is able to contain a large amount of water and provides sufficient water through the water guiding paper. This will allow the palette to retain moisture very well. The palette paper’s obverse side is covered with a layer of PET protection film. It has gone through special processing for easy use and to be impervious to water. What’s more, this product has a water compartment so you can replenish water easily at any time. MTS-024a Palette Paper Refill Pack for Acrylic Paints will be released at the same time. This product will become a great tool for your painting.
