MTN water-based spray paint cans are budget efficient spray cans that are great for outdoor use and they can be used indoor as well. They don’t leave behind an ever-lasting smell like some other spray cans do and they’re 300ML, which gives you plenty of spraying time. The matte finish of these paints is very fine and dry relatively quickly, leaving a fine piece of art behind. If you like, you can even mix these with acrylics when they’re still wet and they still won’t take a long time to try. They come in a bundle of different colors.
