Mylar sleeve vs. PSA holder for preservation

Here you go. You want the sleeves listed as polyester (mylar) on this page:

From the catalog I received with my last order (#38), here are the codes:

SNCDPET 2 3/4 x 3 3/4" 100 @ $23.00 current regular sized cards
S1950PET 2 7/8 x 4" 100 @ $26.00 1952-1956 Topps
STCDPET 2 5/8 x 4 7/8" 100 @ $24.00 GameDay, Fleer Extra Bases, Topps Tall Boys

I am a pretty big fan of Bags Unlimited. They were recommended to me as a solution for my graded T202 cards. Code STT25 4 3/8 x 10". They work perfectly. They will send you their current catalog with your order. Highly recommended.

I hope this helps! Good luck!
