CryptoKitties By the Dozen: OpenSea to Bundle Collectibles for Easy Sales

"We think sellers often struggle to accurately price their items, and bundles allows them to price a bunch of items together when the value of each individual item is unclear."

Like sales of individual items, bundles can either be sold at a fixed price or auctioned.

Bundling - through bulk sales, grab bags and other types of collections - has existed for a long time in markets for analog collectibles.

Further, some new crypto projects are generating categories of NFTs that might only make sense to sell in bundles.

Finzer told CoinDesk how the bundle feature could help one of its partners, Etheremon, which recreates the Pokemon Go experience.

Any new ERC-721 project will be able to sell bundles on OpenSea.

For companies using OpenSea's API to put items into its marketplace, bundles will work through that interface as well.

Plus, OpenSea respects custody; users can play with bundled items on sale up to the moment they transfer ownership.

Speaking to CoinDesk, Finzer said, "There's also recently been a lot of excitement about the bundling feature in the MLB Crypto Baseball Discord. There's already a bundle listed with three entire MLB baseball teams in it."

As of this writing, there is a bundle on sale mixing NFTs from decentralized applications CryptoKitties, ETHTown and War Riders.
