They have both snaps and velcro. When they arrive they come snapped onto the small setting but apparently they can do down smalled to an extra small size but the only way I can seem to do this is to fold down the soft velco bit towards the inside of the nappy which would put the soft velco bit on bubs tummy - surely this isn't right because the edges are a little bit siff and could scratch delicate baby skin?
when I do fold it down like this it looks nothing like the picture but they didn't really come with setting insrtuctions either -

hopefully I have a big enough baby to just use the small setting
