Tristars Hidden Treasures Baseballs

[PhilCam]

I collect memoribillia as well as cards and was hoping someone could give me some information on this product. I assume the balls come with a CoA, but do Tristars make their own or will it be a 3rd party? Has anyone had success or heard of someone having sucess with these? (I'm considering buying the 6 ball case) thanks.

I have boughten a few packs here and there. They come with like a little sheet on the guy who autographed the ball. They have authentication stickers which you type in on their website and thats like their COA. I love the stuff.
