content: I have been using GUM proxabrushes. it is very difficult to find in stores. I usually get them at Wal-Mart. But recently I don't have any luck at all. They always run out of it. I am very glad to find it here. It is even cheaper than Wal-Mart. Shipping is fast, and price is great. I have no compliant at all. In case you don't know. This is model number 614. I assume they want to start using "tight", "moderate", and "wide" instead of model numbers.
