So I just received my order from Luxury Moon, a "limited" edition si-bell, and there's two things that I find intriguing: the first one that I noticed is that I did not get the necklace. What the heck? Does Luxury Moon not send those or..? I thought they already came with the cup no matter where you get it from. But whatever. Second, and most important, I'm holding my cup to the light and I noticed something strange, the cup seems to have those wave shaped stains that showed up on my Iriscup after a year of use, that you can only see when you hold it in front of some sort of light source. Is this normal???
