I don't know about the silver ones.. But the gold ones are about the same quality as other Japanese pokemon sleeves. I'm guessing based on the texture because i've never used them. They aren't really compareable to our prerelease sleeves, the Japanese pokemon sleeves and our prerelease sleeves aren't the same quality. The Japanese pokemon sleeves are more slippery however are very good quality and don't wear as easily as some of our prerelease sleeves.
So they're showcase items
They are sleeves....you play with them on your cards! Now, with some of the rarer sets, you may only use them at certain tourneys like Reg's, Nats or Worlds. I wouldnt risk my "rare" set at league or a BR.

Keith. I have found 55 of the Orange ones for you (in packs of 5 (11 packs of 5, don't get excited))
Had 57 but had to give Ditto 2 when 2 of his split!
We will find the last pack of 5, and then on we go!
