oh, i see what grunk means. i didn't mean that these were museum quality like they are really really good, that's up to you to judge. what i meant was that the materials used are archival and meet most museums standards for display as far as materials go, so if taken care of they will last a long long time.
i didn't mean to sound like a hotshot by saying that my stuff belongs in a museum. i can see how that wording looks now, but i just mean the materials are archival.
