ANACS Clear Box - Anyone know the rough time period these were used??

"My friends who see my collection sometimes ask what something costs. I tell them and they are in awe at my stupidity." (Baccaruda, 12/03).I find it hard to believe that he (Trump) rushed to some hotel to meet girls of loose morals, although ours are undoubtedly the best in the world. (Putin 1/17) Gone but not forgotten. IGWT, Speedy, Bear, BigE, HokieFore, John Burns, Russ, TahoeDale, Dahlonega, Astrorat, Stewart Blay, Oldhoopster, Broadstruck, Ricko, Big Moose, Cardinal.

Sorry-I can't help with a time frame but I wish some of the current slabbing companies would adopt clear boxes for their slabs.
They commenced concurrently or very shortly afterward the intro of the fragile blue holder if that helps
I think they started in 2004 I bought one from anacs in about 2007
I thought it was a bit earlier than 2004.
