Sturdy cutting boards. I see everyone was saying the largest cutting board is medium but I dont think so. I've never had a cutting board bigger than the large one it has so for me, its a large. Love that it is a set of 3 for cutting different things. I used to use my old large one for cutting garlic, which was too big since it would only dirty a tiny spot on my old one and I had to wash the whole thing just for that one tiny spot. Now, I can use the small size for chopping garlic.
