Another awkward strap question. This time for a friend.

Looking for a replacement ladies strap with notched corners at the lugs, so the measurements are 8mm/18mm, with a taper down to around 13mm. Roughly 7 and 11cm long, takes a deployment.

I did come across a website a few months ago where you could order straps and specify the measurements of the strap, and the lugs/notches, but for the life of me can't find it again. It's not in my browser history, and I can't for the life of me find it on google again. I may not have bookmarked it either because I though I could easily find it again, or the prices were so outrageously expensive that it wasn't worth looking at again.
