Would-be gift sent to one of my best online friends, Shirley

It is going to become a would-be gift sent to my best online friends, Shirley
Though this 3-band puzzle ring is of very low value, cost only a few US dollars, I own only two now. The one who sold me this kind of puzzle rings told me there will be out of stock forever just because it is "cheap".
My best online friend, Shirley is a very nice person, who is always helping once she knows I may meet difficulty..(I use present tense since I want to stress that she always helps) . I 'm going to send this 3-band puzzle ring by post as long as Shirley really likes it.
The inner diameter of this puzzle ring is around 15.5mm to 16mm.
