May 6 seems to be 'Free Ring Sizer Day' over at OzBargain…
Are you based in Australia or New Zealand? Simply provide your contact details and we will ship you a FREE ring sizer that will assist in determining your correct ring size. Please wear the ring sizer at different times during the day to ensure you are comfortable with the size. The ring should be snug, but still able to slide over the knuckle.
Thanks Maglia Nera
