Smallest 0.4-Inch Mini 3x3 Cube by Cuberspeed – 1cm Tiny Speed Cube in Blue
The Cuberspeed Mini Lab 3x3 is the smallest 3x3 puzzle you can buy today. At just 1 centimeter (0.4 inches) across, it's smaller than a US cent—yet it's a fully functional twisty puzzle. Designed for both kids and adults, this tiny blue cube offers a surprising challenge for collectors, travelers, or anyone who wants to test their dexterity on a truly miniature scale.
How small is it exactly?
This cube measures 1.0 cm on each side, which converts to about 0.4 inches. For reference, a standard US penny has a diameter of 1.9 cm—so the Mini Lab 3x3 fits comfortably inside that circle. Despite its size, each face can be rotated, and the puzzle works like any traditional 3x3. There is no internal mechanism compromise; it's a real speed cube, just shrunk.
Who is this tiny cube for?
- Collectors – It's a unique addition to any puzzle collection, especially for those seeking world-record-sized items.
- Travelers – Its minuscule footprint makes it easy to carry in a pocket or bag for on-the-go solving.
- Kids and adults – Simple enough for beginners but tricky due to the small size, offering a fresh challenge for experienced cubers.
- Gift givers – Perfect as a novelty gift for puzzle enthusiasts or anyone who appreciates quirky items.
