3Dconnexion SpaceMouse
Useful for moving the viewpoint in Unity.
With one hand, it is very useful for looking at the underside of the skirt or shifting the viewpoint as you dive in.
Personally, I don’t find Unity’s viewpoint movement to be very easy to operate.

MMO Mouse
I use the Blender and Unity shortcuts on the button again for convenience!
I use a G600t MMO mouse!

Ultra Wide Display
In Blender, properties and outlines can be displayed in a larger size while keeping the 3D View wide.
Less scrolling is required so you can work more comfortably.
Recently, it has become possible to buy one for around 30,000 yen, so I recommend it for its affordability.
