I’ve actually seen this one in practice myself. I was at a show back
in February I think. The display looked like any other (standard ring
box with slits). When I went to pick up a ring to try on, the initial
shock of the weighted end was noticeable. I talked with the designer
about it and she’d developed this little trick for just the same
reason. Each ring was tied with fishing line (not sure what test
weight) then attached to a weight below. So yes, they reeled
themselves back in when done. She said that she hadn’t lost one yet.
My personal observations:
#1 Works best for a small display unless the rings are set up in
#2 The line didn’t affect my trying on of the ring.
#3 Need to make sure the ring is securely tied. Heat set or a really
#4 No real inconvience to the seller. Just snip the ring off the line
when the sale is made.
#5 If someone did try to cut the line, you (or other customers) would
probably notice them fooling with it.
#6 Make sure it’s a strong enough test weight or a good pull might
remove the ring.
#7 You could even add a cheap craft bell to each weight so that you’d
hear the ring being taken from the box.
Hope this helps.
