Are you referring to HuCards such as the Arcade Card Pro?
Here is a picture of an Arcade Card Pro, and it's official Sleeve:
My sleeves do not have those two small holes on the right.
If you can fit the Arcade Card Pro into a standard non-hole sleeve, then it will also work with my Sleeves, because mine are the same dimensions as the OEM sleeves w/o holes.
If you PM me your mailing address, I can send you one to test out, if you promise to post pictures of your attempts to get it to work with the HuCards you are asking about.
You can cut some holes in my sleeves, if it is necessary, but I wouldn't recommend breaking-off the tabs in the Arcade Card Pro Case, because that would impact it's resale value.
