Drug Store Knockoffs - MAC make up

My pin today Wet 'n Wild "Walking on Eggshells" trio claims to be the same as MAC "Shroom", "Cork", and "Naked Lunch".  I love these three colors, they are by far my favorite eyeshadows.  After using the Wet 'n Wild trio I found it to be a nice cheap alternative, but have three cons: the pigment is very shimmery in all the colors - even more so on skin, you must use a base eyeshadow to adhere it otherwise it creases and slips through the day, and I could not open the eyeshadow case!  It literally broke my nail, wrecked my polish, and took a knife to open!  It's a good cheap alternative, but I will still be buying the real deal whenever possible - but saving $38 on eyeshadow is really hard to argue with.  Gotta love Wal-Mart!

I STILL CAN'T OPEN THIS CASE WITHOUT USING A KNIFE AFTER A WEEK!
