Children's collection by Kim Kardashian and Kanye West available on Friday

The celebrity couple's childrenswear line will be available from 9 pm CET on Friday on The Kids Supply website, tweeted Kim Kardashian.

"In the last few years, Kanye and myself have designed virtually all of our children's clothes," wrote Kardashian on social media. "We have worked for a long time on The Kids Supply, I'm so excited about it!" said the celebrity businesswoman, who also posted a sneak preview of one of the items on Snapchat: a satin bomber jacket decorated with the word `Calabasas´, the name of the California mansion where the Kardashian/West family lives.

Last February, the parents of North, 3, and Saint, 1, posted the collection's first items on their social media sites. Their daughter North modelled them, and was shown wearing a sequin dress and a yellow overcoat.

The collection's price range has not yet been disclosed.
