This container for my water I got at either Lowes or Home Depot. I think it’s for holding nails or screws etc. It works great with acrylic painting. Two reservoirs for brush cleaning and another I keep just a shallow amount (a quarter inch or so) in it to set my brushes into they will not dry out. It works great for me and will for you. I like using a glass palette also. Real easy to clean. As you see like Golden Acrylic Paints too!
