16mm negative sleeves.

I have been processing my own film lately and was wanting to store my negatives conveniently. I have some old Minox negatives in nice little sleeves. Anyone know of any current sources for 16mm sleeves?

I use the 35mm sleeves but that is a waste, if any one has a source in Australia could they please post it here. I shall try some of my contacts and let you know if I find any.

Dai.
