Product Description

The Pianist of the LittleSpaceman Music Collection
In the quiet corners of the galaxy, Cosmin Keys sits at his piano, composing melodies that drift through the stars. He’s the heart of the Astroband—a soulful performer whose music brings harmony to the cosmos. This nano brick set invites you to build his story, one note at a time.

With 1165 nano-sized bricks, Cosmin Keys is a rewarding challenge for builders aged 10 and up. His detailed piano, expressive pose, and artistic flair make him a standout piece in any collection. Though this set doesn’t include LED lights, its sculptural design and storytelling power make it a luminous presence all on its own.

Whether you’re gifting it to a music lover, a space enthusiast, or a creative soul, Cosmin Keys is more than a build—it’s a tribute to the beauty of sound and the joy of creation. The set includes a brick separator tool for easy adjustments and extra pieces for subtle color variations.

Build the music. Feel the rhythm. Let Cosmin Keys play your imagination into orbit.
