Calling all crafters and DIY enthusiasts! This 5-pack of black foam sheets is about to become your go-to for all kinds of projects. Each sheet measures 12x16 inches (that's 300x400mm for you metric folks) and is about 5mm thick - sturdy enough to stand up on its own but still easy to cut. The polystyrene core is super smooth and perfect for cutting precise shapes, while the PVC film coating makes these moisture-resistant and extra durable. What can you do with them? Seriously, almost anything! Use them for school projects, photo mounting, model building, signs, party decorations - your imagination is the limit. You can draw directly on them with oil-based pens, glue things to them, or cut them into shapes. The black color gives everything a professional look, and since you get 5 sheets, you can mess up a couple and still have plenty left. They're stiff enough not to warp or bend easily, but soft enough that kids can work with them safely (with supervision, of course). Perfect for teachers, artists, or anyone who loves creating things. Just remember - that shiny surface coating is there to stay, so don't try to peel it off! These are seriously versatile and way more useful than regular cardboard.
