NWT Heist "THE FIFTY" 50 Denier Tights - better than Wolford

Heist's 'The Fifty' tights have an innovative construction that's specifically designed for comfort - the seamless style has an adaptive, contouring waistband that prevents digging, sagging and rolling. They've been made in Italy from a lightweight yet durable fabric with an opaque finish. Wear yours with cocktail dresses. - I ordered the 30 denier style but received these by mistake. I have 6 pairs left that are still NWT in wrapped packaging (the packaging says "The Thirty" but they are actually the 50 denier style). The reason I ordered so many pairs is because I love them so much! They are seamless and have such a comfy waistband. These are all size Small. Currently sold at Nordstrom for $50 each. I’m selling for $20 per unit.
