As someone who probably owns over 50 pairs of cufflinks, I really like this case.  In fact I own 2 of these, they are made of good quality and have held up well on repeated travel on cruises and international trips, it's a nice compact size that you will not notice in your carry on or luggage.  I generally use it for all my sterling silver Tiffany cufflinks (which after a while I tend to use more then all the rest).

It also fits one or two pairs of the knot cufflinks, which are great for a slightly more casual look.  You can also use a single compartment to put some pills in, like Valium for sleep on long flights, or a few aspirin for that occasional hangover after a wedding.

I would definitely recommend this product to others as the perfect travel cufflink holder.  Having separate compartments helps ensure that your pairs will stay put so they are easy to find later.  Also, I like that the top is a cushioned form fitting top, so none of the cufflinks will move easily plus it may possibly help slow down the oxidation process for your silver cufflinks.

The fold over snap button has held up well over time.  I've had these boxes for about two years and still very happy with the look, feel and form factor.  If you're a frequent traveler you can't beat the functionality and having 8 seems to be a great compromise for not to small and not to big, but just right.
