Opening all those shrink wrapped card packs
There are a lot of card packs to open, and to ensure you don't damage your cards when opening them, I suggest you use the methods shown in the videos below, which gently breaks the plastic shrink wrap.
In the first video, I'm even a little more rough than you should be (and I was doing it with one hand while holding the camera with the other), but it still kept the cards nice and damage-free.
In this next video, I show how to open an artpack much more carefully. First I found which edge has the seam of the plastic, then I rubbed back and forth a few times in order to break the seam. Once the seam had a break, I was able to peel off the plastic. Again, I had to do this with one hand...it's much easier with two!
Because the cards have print up to the edges, using a fingernail to open the packs could result in damaging the cards, so please be careful as you open them...take a few extra seconds to be gentle with the cards!
