Okay, I just saw this on AIM recently. Had no idea they came in, I tend to check their site periodically... This is the first I've seen of them:

Whoever is responsible for the 'Sold Out'ness, please fess up now and give us a report of your findings!
How are they? Comparable to the Bulgy ((10))?
What is the 'extent' of the 'metal reinforcements'?

the ones aim had were junk. i bought 15 of them and returned them the same day due to looking like they were dragged behind a truck. springs are weak as well.

id rather have 3-4 surplus steel mags for the price. aim is good people.

I picked up a few of them. They were no more used looking than any other surplus mag I have bought. If I understand what I know about these mags they are test mags produced by Finland for their service rifles. They developed different colors of mags to see which plastic was strongest. Black mags won out and became the ones they issued out. The some of the various colors of green mags were sold to the US or something like that. These mags are only reinforced in the feed lips and locking tab. Bulgarian mags are superior to the Finnish because they are also metal reinforced in the spine and the endplate. Even though the Bulgarian are better I think the Finnish are more collectible.
