I love the pink series but I find it a bit too much and the lock puts me off after I saw the same one on the Perforated Musette, it doesn't seem too functional to me... ;-P
But the lock design is actually pretty cool, IMO. You don't actually unlock th lock as you would a normal one, it's actually lifted and the flap comes out like a turn-lock kind. Am I making sense?? ^_^;
