Welp, TRL still hasn't sent me any sort of refund for these mis-sized rings they sent me. They claim to have sent it via paypal, using the merchant services, but the money never showed up in my account and they don't seem to care very much.
On the other side, Blue Buddha Boutique delivered a set of colored rings rather promptly and politely, and a few extra rings. I'm... not sure why they sent me 5 extra rings of a different size and totally different colors, but, y'know, that's not a bad thing, just confusing.
Despite having prices as high as 4x more than TRL for certain items, these rings appear to be actually usable. No matter how little I'm paying for TRL products, if they aren't usable then there's simply no business. -$20 to TRL and +1 to B3.
