I just added this album (which is amazing!) to the database. It's the first album produced by the circle Hinoki no Tow (ひのきのとう). It contains tracks composed by a variety of artists, several of whom are in the VGMdb database, including whoo, PinocchioP, Onyx Kobayashi, nio, and mamomo.
Information about official readings of the artists' names comes from the various websites/Twitter accounts that are linked in the credits section on this page:

The reading "Hinoki no Tow" (instead of Tou) comes from the URL of their official website here:

In regards to the packaging, it contains 7 cards with an illustration on one side and lyrics on the other. The 7th card has lyrics on the front and the album track list on the back.
These cards are all stuck inside a semi-transparent printed envelope. The disc is a CD-R with a high-quality print on the front.
The album was pre-released at M3-2018 Fall (秋) on October 28th, 2018. It can still be purchased from them from their BOOTH page.
