They fold nicely and have a good feature that allows it to also stand alone, but otherwise I've been disappointed.
My primary issue is that the white card easily gets marks from the necklaces, which takes away from the quality of the overall presentation. Additionally there is not feature to hold the chain on the inside of the fold so unless you tape it or add a plastic pocket for your chain, it will fall out. Finally, it doesn't at all have a grip on the chain when you place it through the holes so it just slips down and droops.
I wouldn't buy this product again, although I did appreciate the customer service of the company and I would try them again for other products.
