Correcting Typewriter

Does any company still make the correction of the squares of paper for use with typewriters?
I used to use this White Ribbon precursor place during the 1970s and found useful. I'm about to buy a manual typewriter (I'm not kidding here) to my work and I wonder if there is any company that still makes this product and if so where I could buy it from. I hate liquid correction fluid and dry matter, it would useful for my purposes here. Thank you.
The brand-name is Wite-out, and is now owned by Bic. View out.com www.wite.
