Sure thing. Looks like you got a good selection.
Removal is pretty much as I describe in the blog post.
I grab the clix base with pliers to get a better grip and keep from cutting myself. These things are squirrelly. A vice would probably be even better. Then I take a chisel blade heavy Exacto knife and cutting downward onto a cutting board I slice in around the edge of the integral base.
Older Heroclix were easier to remove as they were glued flat to the clix without an integral base. However, these days they usually have an integral base that fits over a raised bit on the clix base so if you want to preserve the integral base it's best to work your way around the edge before you try to pop it off.
Of course if you don't care about the integral base, the vinyl they are made of is soft enough to simply cut under the soles of the feet with even a light Exacto blade.
