Not all Personna twin carts are made in the USA. They are also made in Israel.I've used the personna blades in my Trac II for a number of years. Gillette has moved production to China, South Korea, and now Poland. The quality of these blades are down, but not the price. Personna is American made, good quality, CCS, and a bargain. Cheaper than a Gillette disposable.
Personna, Wilkinson, and Schick are the same company. Most Equate razors are Personna.
