imnot positive. i bought some on ebay and am listing the extras i have on here. i will look tonight and if i can find out i will post. sorry and thanks
it doesnt have a name (like clear blue on them), i can check when i get home to see if there is a company name somewhere, but i may not be home before the auction ends. I have bought them alot and found out I was pregnant 3 times using them over the years.
