I bought it at the same time as I bought a new frying pan. I had been using a set of tempered glass lids with a frying pan made by another company, but they were heavy and even though they were supposed to be able to stand up, they would easily fall over, so I wasn't happy with them. When I was looking for a new frying pan, I saw an introduction to the frying pan and lids at Nitori Live, and when I checked them out at the store, I was impressed by how light they were for their size, so I bought them straight away. There are many frying pans that can be stood up, but when you want to put them away, it's great that the handle can be folded flat and easily stored. There are three different sizes, so it's easy to buy one that matches your frying pan. I recommend you go to the store and check out the lightness and ease of use for yourself. I highly recommend it!
