DMC 6-Strand Embroidery Cotton 100g Cone-Baby Pink Light

I brought 4 cones 2 years ago, but not use them until recently. 2 cones are real DMC floss, but 2 cones are counterfeits, not real DMC. I've been using DMC floss for more than 10 years and know how it feels like, the fake floss is obviously harder and thinner than the real DMC product. The counterfeit cones are 819 and 666. I am disappointed a store like Walmart sold counterfeit products. This was not sold by a third party seller, but by Walmart.
