Background
On March 23, 2016, Pledis Entertainment announced they were to debut a new girl group, temporarily called Pledis Girlz. 7 of the 10 members, Eunwoo, Kyulkyung, Nayoung, Rena, Roa, Xiyeon and Yuha, previously competed during the first season of Mnet's survival show Produce 101, where Kyulkyung and Nayoung became finalists and debuted as part of the group I.O.I. Meanwhile, the remaining members held weekly concerts to promote the upcoming group.

The last concert as Pledis Girlz was held on January 6, 2017, where they revealed the official name of the group to be Pristin. After I.O.I disbanded, on January 29, the 10 members were finally reunited.

Release
On March 2, the first teaser image was revealed, confirming their first mini album to be released on March 21. The schedule for their debut was unveiled on March 7, while the tracklist for the album came out on March 13. The next day, on March 14, a highlight medley was also released on the group's official YouTube channel, featuring a preview from each song of the album.

The EP was finally released on March 21 through several digital retailers, including Melon in South Korea, and iTunes for the global market. Physically, the album received two versions, Prismatic and Elastin, the words that originated the name Pristin.

The first single "Wee Woo" was used as the title track to promote the album. It was released on March 21, along with a music video.
