hmm, i would be wary about using the hair straightener method, especially if you have an expensive straightener. unless you only have 1 or 2 to depot, i'm not exactly sure whether keeping your hair straightener on for so long to depot your nyx e/s is a good idea. since the straightener is generating a lot of heat there's a chance that it might get burnt out... i say this b/c i've tried this method before with my HAI straightener and ever since thing my straightener has been acting a little funny.
what i like to do is take a pipette, fill it up with alcohol, and inject the alcohol into the cracks in between the square e/s pan and the plastic container. afterwards, i let the e/s sit for a bit, letting the alcohol dissolve the glue and then i take an exacto knife or paring knife and lift the pan out of the pot.
and then i put it into a mac pallet.
hth.
