This listing offers one pricing dimension: Product Access, measured in units. It is a free subscription that grants you access to the Kelly Bag Heritage Index (KBHI) data. There are no tiers, instance sizes, or usage add-ons to choose from. You subscribe once and receive access to the product. Because it is free, there is no cost that scales with quantity or usage.
Top-of-mind questions for buyers
What does one unit of Product Access grant me?
One unit grants access to the Kelly Bag Heritage Index (KBHI) data on the subscribed account. Access begins once you subscribe. Since the product is free, adding units does not create a cost that scales with the number granted.
What kind of data underlies the Kelly Bag Heritage Index?
The index draws on auction and private-sale records for exotic-leather handbags, including sell-through and value trends by house and quarter. Figures reflect realized sale results rather than asking prices, and the underlying dataset is refreshed as new results come in.
How current is the Kelly Bag Heritage Index data?
The handbag dataset behind the index updates daily as new results close from auction houses worldwide. The record covers realized transactions over roughly two decades, so the index reflects recent sale activity rather than static or estimated values.
