Ikea Smorboll Duvet Covers Blue. This for 2 Duvet covers of unconventional size. They are both 60 in x 72 in. Regular twins are 64 in x 86in. One of the covers has a small hole near the snaps (see picture)  this same cover doesn't have the traditional corner (see picture). It looks like someone has taken a larger duvet and made it smaller. All seams are serged. Maybe these fit nice in a motor home? I have no idea!!!
