White sticky labels (Headington OX3)

I have a large number of rolls of sticky labels, e.g. for use as address labels. BUT each 80 mm by 95 mm label is split into 12 smaller labels, 11 of which are 20 mm by 25 mm and so too small to be of use (probably - you may have a use for them which would be good). There is one 40 mm by 50 mm which is a useful size.
