Marcador de Livro Einstein em Metal

I keep fidgeting with it during meetings, the die-cut pattern flipping between chaos and Einstein's face depending on the light, and it's genuinely mesmerizing. Solid metal weight means it stays put in my notebook, and it's already sparked a few fun conversations at my desk.

The way the grooves shift from abstract lines to Einstein's face as you tilt it is genuinely clever, and the die-cut detail is razor sharp. I keep it propped on my desk just to watch the perspective change when the light hits it.

The metal feels heavy and sturdy, and the way the grooves morph from abstract lines into Einstein's face as you tilt it is seriously clever. I keep it propped on my desk just to play with the optical illusion between chapters.
