How is the sealed product price tracked?

We track sealed product prices daily and blend them into an Inkwell Fair Value. The chart shows historical price movement over time.

What does the value ratio mean?

The value ratio compares what you can expect to pull from the product (or, for products without a pack model, the total value of the set's singles) to the product's price. Above 1.0× means the expected singles are worth more than the price.

How often are sealed prices updated?

Sealed product prices and the value ratio update daily as part of our automated price pipeline.
