SOME of the dice have foam damage already (the ones that were still in the original packaging) so I wouldn't have an issue with those.

I can't imagine that the foam being under the velvet would cause an issue, but then again fumes and other "invisible" byproducts of the breakdown process can still occur. I'll look into a few other ideas.

Would love to find a place that sells the vial containers found here...

Thanks for the input regarding the enamel as well. I'm pretty fortunate in that there's very little crystallization on any of them. The "Certified Perfects" all seem to have the same amount on the exact same corners, but it is minimal right now.

I am a bit worried about living here in the desert and not having a place that is constantly under 75 degrees though. We're among the folks out here who do not have the A/C running every second of every day so I will have to find some place reasonably cool and hope for the best.

MANY thanks for all the info. It is truly appreciated...even though you won't give up your El Rey tie or dice. LOL
