I've noticed more and more pouches available in the general marketplace. Wallymart now has some about 4 inch x 12 inch in different colors, Home Depo has a great 3 pack different size deal with a see-through mesh section (not a whole side). And from what I have used, they are very durable. I guess people are finally finding more uses for them. I still attribute it to know the TB pouches were on the market first though. Start another trend!
