I quite like these in the beginning, as I love the bright matt white, but I buy in bulk and my last 50 packs have lost their stickiness totally, almost like paper, and that is due to heat fluctuations Ive been told? We get quite warm here in WA so I would have moved them to a cooler room if I had known about this issue. Working from home I only have the aircon on in my lash room when working. Julia was great at rectifying the issue for me though.
