Hey crafters and artists! If you use those ink blending tools, you know the foam heads eventually wear out - well this BAOFALI set has you covered with 10 replacement foam heads plus these super handy stackable storage containers! Each foam circle is about 1.3 inches across, which is the perfect size for most ink blending tools. The foam quality is seriously good - it holds ink well and applies color smoothly without soaking up too much product. But here's the brilliant part - each foam comes with its own clear plastic container that stacks with the others, so you can organize your colors and keep them clean between uses. The containers measure about 7.5 by 0.5 inches, making them perfect for storing in your craft drawer or taking to classes. Using them is simple - just attach a foam to your blending tool, tap it into your ink to load up color, then swirl, dab or rub it onto your paper. When you want to switch colors, just pull off the foam by the edge and attach a fresh one. Cleaning is easy too - just rinse with a little dish soap and water when you're done. These foam refills are incredibly versatile - use them for creating card backgrounds, applying ink to paper edges, working with stencils, creating ombre effects, inking up stamps, or heat embossing. The foam applies color evenly and blends shades beautifully for professional-looking results. Whether you're into scrapbooking, card making, journaling, or mixed media art, having plenty of fresh foam heads means you can work with multiple colors without cross-contamination. The stackable storage system keeps your workspace organized and your foams protected from dust and damage. No more digging through messy foam piles or struggling with worn-out blending tools - this set gives you everything you need to keep your ink blending game strong. The value is amazing considering you get both the replacement foams AND the storage solution in one package. Your craft projects will look so much better with fresh, high-quality blending tools that apply color smoothly and consistently every time.
