The Hobbyzone OM02ui is an insert designed for the drawer of the OM02u unit. It functions as a brush holder and storage case for brushes. The brush holder can be used directly from the unit after opening the drawer or can be standalone on the table.

The spacers that support the brush holder in the drawer allow for the use of the space beneath the holder for storing brushes. Brushes are stored horizontally both in the storage space and on the holder, offering a significant advantage.

The set also includes two disposable palettes for use in modeling activities related to painting. The accessories depicted in the photos and the OM02u unit are not included in the set and are for demonstration purposes only.
