The NARS ones were pretty easy. I have a candle warming plate that I use for the heat. I just set the whole package on there and waited for a minute or two. I didn't disassemble the packaging, just let the whole thing warm up. I have an X-acto knife that I place on the side of the pan and just apply the smallest bit of pressure. If it sounds like the glue is loosening, it should slowly pop right up, if there's no sound, I put it back on the plate for a little longer. For me, it helps keep my diligence with getting the pans out. Sometimes I just keep applying pressure and that's when the product cracks or crumbles!
That's part of the reason I depotted those three, too. I have the Tres Cheek and a bunch of coral shades, but these three were kind of their own grouping. Eventually, I'll get more colors to compliment them, but right now I have a majority of brights, pinks, purples and corals.
I also depotted all of my Urban Decay single shadows today. I only had one casualty, and that was Urban Decay's matte eyeshadow Chronic. I just chipped a little bit of the edge as I was prying the plastic plate out of the package to set it on the warmer. It's still mostly in tact, though! Mattes are pretty crumbly, if you're not careful. By that time, Chronic was one of the last ones that I was getting out of the packaging, and I had depotted 30+ pans beforehand. I even depotted one of my Vera powders, but then I realized that not many pans that size fit into a large Zpalette! I'll have to try out the pro Zpalette and see if I can fit some powders in there.
Ohh I also depotted my Lightscapade! Without a hitch, I was so proud lol, then I put it in the regular Zpalette and of course I hadn't used enough of the product for it to fit, so I put it back in the package, with it loosely in there, but the benefit is that I don't plan on traveling with the MSF, even if I do use it everyday. If I go on vacation, it always stays at home
