Mine is a cheap, quilted, zipper pouch in an animal print. It believe it is a cotton/poly blend. I turn it inside out and machine wash/dry it twice a year. I've had it for about 5 years. It was a drugstore purchase.
My makeup bag is not the most fetching thing in the world, but it has held its shape remarkably and shows no signs of wear. I'm so immensely satisfied with its performance; the quilted fabric protects and cushions my makeup (nothing has broken and turned powdery, ever) and even my pointy manicure tools have never poked through. I just love it.
The brand is Americana by Sharif.
