Product Description

The Tender Soul of the LittleSpaceman Fleet

In the vast silence of space, Cosmin Heartlight glows with quiet courage. He’s not the fastest, the strongest, or the boldest—but he’s the kindest. With a glowing heart at the center of his suit, he reminds us that even in the coldest corners of the galaxy, warmth can thrive.

This nano brick set invites you to build Cosmin’s story in just 378 pieces. Standing at 4 × 9 × 9 cm, he’s compact but full of character—perfect for desktops, shelves, or bedside tables. A single LED strip illuminates his heart, casting a soft glow that turns any space into a sanctuary.

The set includes a clever brick separator tool to help you adjust misplaced pieces with ease, plus extra bricks for subtle color variations. Want Cosmin’s heart to shine in pink today? Or maybe he’s sending love from a distant nebula. You decide. Batteries are not included for safety reasons; the LED strip requires 3 LR44 button cell batteries.

Whether you're collecting the full LittleSpaceman fleet or gifting Cosmin Heartlight to someone who needs a little light, this build is more than decoration—it’s a message of love, hope, and cosmic kindness.
