Ring Sizer (1 ratings) £2.00 Quantity: at £2.00 each Add To Basket 5 in stock. The most acurate way to get your ring size is to visit a jeweller and be professionally measured. However, if you are unable to do so I can send out a plastic ring sizer for you to measure yourself. The cost of the ring sizer will be refunded on the purchase of any ring within 6 months of date of purchase. The responsibility of providing an acurate measurement is yours.
