How are Alter Sleeves made?

We print on Dragon Shield Perfect Fit bottom-loading inner sleeves. They are PVC and Acid-free.
These are primed by hand and then printed, each sleeve is carefully examined to make sure the product that reaches the customer is the highest quality we can produce.

If you have an Alter Sleeve in a deck and the rest of the cards are in Dragon Shield Perfect Fit inner sleeves, it should be indistinguishable when double sleeved.
Alter Sleeves should fit in any Outer Sleeve that Dragon Shield Perfect Fit sleeves work in.
Note: different brands of outer sleeves will fit differently around the inner sleeve.
