Tamashii Nations will release two palm-sized figures of Nezuko and Kanao from Demon Slayer. They are part of the Figuarts Mini collection. They will come out in November 2021, but pre-orders will start on July 2, 2021. Nezuko will have an alternate expression, whereas Kanao will have extra arm parts. Each figure costs 2,970 JPY, which is approximately $26.75. [Thanks, Famitsu!]
Both the Kanao and Nezuko Figuarts Mini figures stand at under 100 millimeters and come with a special stand for you to place them on. Nezuko has a simplified chibi-like design, and she has two expressions. She has a neutral face and one where her eyes are cartoonishly closed. The mini Nezuko figure is based on the chibi version of Nezuko when she shrank herself to escape Kanao in episode 21 of Demon Slayer.
Speaking of Kanao, the Kanao figure is, like in canon, less expressive than Nezuko. However, she comes with two additional right arm parts to change her pose. She has a neutral stance, a stance where she is holding a butterfly, and one where she is holding her nichirin sword.

As the heroine of Demon Slayer, there are plenty of other figures and merchandise of Nezuko coming up in the future. For example, Good Smile Company will release a Harmonia humming doll in Spring 2022. The Nezuko Harmonia humming doll is currently available to pre-order.
The Figuarts Mini figures of Nezuko and Kanao from Demon Slayer will open for pre-order from July 2, 2021 and will release in November 2021. They will cost 2,970 JPY each.
