"They're real and they're spectacular!".
I took the plunge in 2017 after not committing because of the cost. In fact, I initially purchased a second-hand small case and tested whether it would hold coins in a stable manner. The test
met expectations and several subsequent acquisitions followed.
There are other decent products and perhaps the main difference for me is that the Abafil products have an appearance that is more consistent with an ancient coin
collection, particularly for coins that have not been doomed to spend eternity in plastic cases. (Not that I have a preference....) They have handmade components but have tight mechanical hardware. Some very nice competitors have plastic versions, but they do feel like plastic. Abafil trays are primarily
wood, silk and other natural fibers, although most case exteriors are not natural material. I think the latest version have exposed-wood trays. There is no flex to the tray, unlike some lower-cost all-plastic models.
See Andrew McCabe's spectacular on-line
collection and many similar presentations on this board for the visual appeal of the trays. On the other hand, if you do not show coins to other people, or primarily trade and sell coins, these cases are probably not as appealing.
Both the
Italian manufacturer and a primary US retailer are very responsive.
The velvet surfaces can gather dust/lint/mysterious
flecks if not kept in the cases (or if you eat breakfast while sorting). That can be cleaned out with compressed air, such as keyboard cleaners.
Here is an older half-sized tray of Republicans for amusement.
