There are two collections if you would like to append.

File > Append > (The Illusory) > Collection >

> Scene Equipment - (This is the studio setup as seen in renders including the model) if you wish to only import the model select :

> Model - (This is the sculpture exclusively, for use in your own projects) 

The .Blend file is inclusive of all textures, if you wish to use OBJ or FBX use the included textures folder to re-link. All file names are named and managed to ease the process.
