correct. if you buy them in a TIN, do NOT open them (if your intent is to age them).
if you find a blend you like that's sold in bulk (cheaper/larger amounts), then you can seal them in large mason jars.

my tins are on my closet shelf... not on display, etc. there are some ppl around here with hundreds of tins, and probably 20+ lbs of bulk sealed in jars. so, having all that on top of your humidor would be difficult to pull off.
