Berkshire Relief 30 Pantyhose are model 8101. The packaging has been redone so you might not recognize this product in this package. These have light leg support, very good control top, and a reinforced toe. Berkshire make quality products known for having a good fit. 80% Nylon, 20% Spandex. The product I have in stock is from a new batch that just came in June '22. These are different than the old Berkshire's, though they're the same model number the control top isn't as strong as it used to be. But a customer did tell me they're comfortable.
