The first token is located directly above you on one of the ceiling fan blades.

Slide the chair back from the desk. You'll find the token on the floor, right at the center of the carpet’s design.

There's a pattern drawn on the right-side wall of the drawer cabinets. You need to open all drawers except the middle one and the top number 10. Once that's done, the middle drawer will open itself, revealing the token inside.

Look below the left side of the wall map - there's a loose plank on the floor. Remove it to find the token.

Stand in the middle of the room and face the desk. The token is inside the nameplate.

The token is hidden beneath the bottom drawer, located above the sofa near the main door.

Inside the photo printing room, the token is located just above the entrance door - specifically the left window, in its bottom-right corner.

In the same photo printing room, behind the open door, there's a radiator. The token is on top of the radiators valve.
