I have found (in my sewing room clean up!) an older style NIGHTZ, it
has orange snaps but they are not hidden like the newer ones. It is
marked a second as the hidden flannel layer is still leaching small
amounts of dye despite several prewashes (to the flannel only, not the
whole nappy) so the nappy may end up a mottled pink colour. So far this
has not caused any problems with dye running into other nappies in a
load.
This nappy will appear on Ozebaby as 'NIGHTZ 2nd' and will be quite
well reduced in price. I dont have a picture of this exact nappy but it
looks the same as all the other NIGHTZ do and as stated has orange
snaps :)
