10 Ultra-Pro PSA Acrylic Slab Stands...These are well made Beautiful Stands for your PSA Graded Cards. Note:
These stands will NOT fit cards graded by PSA that have the NEWER cases with the HOLOGRAM in the center of the label. I bought these figuring they would fit all PSA Graded cards...They do not...They fit all PSA cards but the newer most recent designed slabs with the hologram in the center. ...Priced Right
HOWEVER:
I found this
