Please note this bag and its padded insert are flexible - especially front to back. It's one of the best things about the bag! Therefore it can fit items slightly larger than the dimensions suggest - inside it could comfortably bow out to a 'D' measurement of 100mm at the bottom and 120mm at the top (at the centre) for example, at a stretch it can go out to 140mm (5½").
