Comes in a Topps sealed snap case with certificate from Topps. Players include Griffey, Jeter, Ripken, Bonds, etc. The only real dud is Jose Cruz Jr. Each set randomly contained three refractors and one atomic refractor. This led to most sets being cracked. With only 900 of each card that means there are only 150 of each refractor and 50 of each atomic refractor. The only visible card looks to be the atomic refractor of Garciaparra, still leaving 3 chances of pullling a very limited card of a HOF'er or other great player. Not going to find many of these still sealed.
