Old adhesive [SEP] The short version: the adhesive backing on these sucks and I think it's because they've been sitting a long time. I put them on and 20 minutes later they were falling off as I did simple things like put on clothes and pack a duffel bag for the weekend.<br /><br />The long version:  I have a feeling these are sold on Amazon because they are no longer sold in stores or on the website for the company- which means they're pretty old. Over time, press-on-nail-adhesive like this seems to get less effective. During isolation I stopped wearing Kiss Impress nails because I didn't need them, but my old stock is now broken out again and it seems like every pair I let sit for a year no longer sticks through a few days of use, let alone the two+ weeks I could get out of them before. New purchases have not let me down like this. I tried using Kiss liquid nail glue, but that didn't help at all, which is strange, since it's usually so effective for me.
