Ive got M44-7's they have that little plastic cap covering the needles, i flip that down, and stick it in a small digital camera case, although i do want something squash proof, what about them dominoes boxes, where u slide the lid off? oh shit ive got one, if u ever buy blue Jeans aftershave, it comes in a small metal cylinder just big enough for too, that could work. im gonna keep thinking cos i need some for myself
