I decided to expand my ring collection yet found that when I tried on my items (without the fangled packaging), it didn't fit and just slid right off! So off I went to Amazon to see what (if any) new inventions they had to assist people in my dilemma. Fortunately, I came across this handy product at a cheap price, compared to high street stores. It works really well the rings I bought, however it is of vital importance to note that because of the diameter of the inside of the cylindrical ring tube, it may not fit properly on dainty bands. It would be a good idea to check measurements (if they are available that is) before purchase, to avoid disappointment.
