Two things did impress me. One is the packaging - it is wrapped in tissue so that none of the rods touch each other. The rest of the CIM glass comes in tissue sleeves - but they do nothing except keep the glass together. This is a full wrap and roll, so that the glass is not rubbing and scratching in transit and storage.
Second thing that impressed me was that I actually manage to encase silver foil and keep it looking silver, without it developing a gold cast.
I have also used in in quite a few beads with a lot of metals, dichro, long working times, etc., and had no problems with cracking or compatibility.
Looks good!
