Haven't been able to figure out way to receive mail -- I'm in a sublet, and moving into another one for the next six months. Any ideas, or know of a place where I can buy it in person?
There are a number of school supply shops in recoleta that I've found that carry them. Mostly on or near Santa Fe. Specifically near Uruguay and Santa Fe. I know this is not super helpful, but I can at least affirm you can get them.
