I think that's what they are called...I just ordered my course haven't gotten it yet. But I had one of Marie's people come do my apartment and am now moving. Since I have these rods all over my house (I believe they are copper) I'm wondering if I should save and reuse them in my next place or someone elses or is that a no no? Are they reusable? And if so, do I have to cleanse them in any way? Thanks! I'm trying to find out before I leave, so I can trash them or take them with me and I think the course may get to me too late to look there for the answer!
