Very cool tool for Meta Quest. My experience is that it provides much higher precision and control for apps like Adobe Modeler and Gravity Sketch. Charges with included USB C cable.

From manufacturer:

MX Ink is natural and delightful to use with responsive and adjustable, pressure-sensitive tip and pressure button, your paint brush can feather and widen, your sculpting can dig deeper, your notes can be emphasized, and more. From work to play, MX Ink can bring your imagination to life without friction.7.

The potential for creativity in Mixed Reality (MR) is maximized with masterfully engineered high-precision controls. Perfect placement for pen and wand articulation includes 3 controls at the front, tip for 2D interactions, Meta button at the top, and haptic response. Sketch, grab, move, and manipulate objects in virtual space—even in context with physical space.
