I just more or less completed my Thunderstone Advance collection at a recent garage sale. My collection, previous to that, is not yet sleeved but the new addition to the family (ToR w/ CoB) is already sleeved with what appears to be UltraPro 2 5/8" x 3 5/8 sleeves. I know the make is UltraPro as it has the hologram logo on the other side i.e side not pictured below.

The UltraPro site does not seem to have anything like this.

Some have a matte finish on one side like the one picture below. I would gather the intention is that you could have a glossy side or matte side facing you depending on preference? These do not feel like penny sleeves (which I did find in this dimension on Amazon) and I do not want those for this. I am having a hard time finding more of this dimension. These are larger than standard Magic the Gathering cards.

    They appear to me to be Ultra Pro’s Pro-Matte sleeves in clear, which I myself use for certain things. One side is glossy, the other matte. And sleeves made for Magic will fit TA cards according to this thread: boardgamegeek.com/thread/822554/card-sleeve-size

    After talking with m FLGS they also came to that conclusion. @user30903 If you flesh that out into an answer I will accept it.
