I was using several smaller cosmetic-type zipper bags to move my things from purse to purse, so when I saw this product, it looked as though it would do the job a little more easily. I don't know if I'll ever be able to find that out, however, because the inserts have such a strong chemical odor that I do not want to put them into any of my purses. I've tried spraying them with Febreeze and setting them outside to air out, and I have also sent them through a machine wash with extra detergent, but the odor persists.
Perhaps over time, the smell will finally dissipate, but until then, I can't review the performance of the product. It's too bad, because the insert looks as though it would be quite useful... if only it didn't smell like a vat of dry-cleaning fluid.
