If you're like me and love to create things, these foam blocks are great for so many things. EPS can be messy to work with if you don't use the right tools (think of thousands of little foam beads that cling all over your clothes because of static), so if you haven't used it in the past be sure to look up some tutorials to get clean cuts and smooth edges. That said, they're a bit on the pricey side for what is essentially two big blocks of Styrofoam, but you're not going to find blocks of this size amongst packing materials and the like.

We used this to make a moss bowl, but it was a huge mess to cut these. It got covered by a moss sheet and other pieces of moss, so it’s not like you a see it. So, for this it was fine, but I guess you would need a dremel or something to cut and shape smoothly, as opposed to a knife. The description made me think it was going to be softer/ smoother and easy to slice, but oh well
