I am on my second one I bought #1 when it first showed up on your website. The zipper is a problem and both have had that challenge. I tossed #1 and bought #2 but the elastic to hold the bottles is loosening again. I try to be careful when I have oils on my hands and I try to remember to wipe them on a tissue before putting them back in the elastic; but over time they lose elasticity. The bottles in purse #2 are looser and drop out into my backpack easily if I am not diligent about zipping it up. Zipping is easy to remember when all I'm touching is a roller bottles but it's at the grocery when I'm reaching into to get my debit card/cash and swipe it and tuck it or the change back in and toss then unconsciously drop the clutch in the backpack. I wish I had a great suggestion, but I don't.
