The “Caitlin Clark EVO NXT 3951 Game Basketball” is a custom design with writing across the Wilson logo referencing a note Clark wrote as a kid.

Caitlin Clark’s official Wilson basketball collection is a best-seller.

With four basketballs available ranging from $25 to $100, Clark joins an exclusive club that only has one other member, according to USA Today: Michael Jordan.

The various basketballs boast unique designs, differentiating them from each other. The “Caitlin Clark EVO NXT 3951 Game Basketball” sees writing throughout the Wilson text on the ball. The written text comes from a note that Clark wrote in the second grade, the note saying “Get a basketball scholarship. Play in the WNBA.”

Other models offer varying colors and copies of Clark’s signature on the ball.

“It feels surreal to have my own basketball collection, and I hope it inspires the next generation of boys and girls to pick up a ball and play,” Clark said in a press release.

While the inventory sold out quickly online, Wilson says that more will be available in August.
