This is brand new (with tags) Limar air Atlas helmet. Size S - 52/56cm. 255gr - without mips version Never worn. I only tried it on my head to find out it wasn't my size. The box is slightly crushed as it was a little bigger and it was hard to fit in my backpack, so I pressed it down a bit. CAUTION! The sizing seems off. My head is 54cm around. So the 52-56cm size Air Atlas was expected to be fine , as it is with practically every helmet. But it turned out to be big. To fit me I have to close it all the way down to 52 with no room for fine adjustment. I've read the forums and it appears this is a common problem with this model. So I think if your head is a bit bigger than mine (say around 55-57) it should fit you better and you can adjust the sizes more precisely.
