I have been buying these bags for years. But until this year, I always bought the white mesh as I worried about bleaching being a problem for any of the other bags. It has been a busy time for our company and in January I needed bags shipped immediately for my last order. When I found out they were out of stock on the white bag, I called the company. Isabelle assured me that any of the bags with colors can be bleached, there will be no ink bleeding, etc.... She was right. I have ordered twice since then, and now am using three different colors- Blue, orange and green. No problem. (I always purchase all three sizes, the small, medium and large). Highly recommend.
