Update by user Aug 16, 2019 Well, now I feel pretty stupid - the team at LilySilk reached out and confirmed that the label is authentic, as the string "SHHO 113399" works on the label checker. I'm still not especially impressed with the quality of the product or their social media practices, but clearly they are at least honestly advertising under the Oeko-Tex label. Original review posted by user Aug 16, 2019 LilySilk is committing fraud and engaging in false advertising practices, plain and simple. Aside from the fact that their alleged silk products feel nothing like the actual texture of mulberry silk, I have photographic evidence that they are using forged Oeko-Tex certification labels. Attached you'll find an image of the fake Oeko-Tex label on my "silk" pillowcase, which bears the alphanumeric code "SHHO 113399 TESTEX" and comes up as invalid on the official Oeko-Tex label checker (available at https://www.oeko-tex.com/en/label-check). It also doesn't match the standard format of authentic Oeko-Tex labels, which normally consist of an 8-digit code followed by the word "Institute." In addition to creating these fraudulent labels, I believe they're also listing a shell company address on their Google My Business page, claiming that the company warehouse is located in Diamond Bar, California. In reality, their products are shipped directly from China. They've also flooded multiple social media channels with positive information about their company, and attempted to bully anyone who leaves negative reviews, albeit in barely coherent sentences. I would not be surprised if they create shell accounts just to respond to this review. If you're looking for proof that this company is a waste of your time and money, you've found it.
