Most infinity cubes are made from plastics (commonly ABS or other generic plastics); some use TPE. Construction can also include metal rivets and internal rare‑earth magnets for the folding/locking mechanism.
Many cubes are labeled for school‑age children—common listings show 5 years and up or 6 years and up—while some simpler fidgets and shapeshifting cubes are listed for ages 3 and up.
Some cubes use mechanical hinges with metal rivets for folding, while others rely on internal rare‑earth magnets that lock pieces together to hold shapes.
Some shapeshifting cubes advertise dozens of configurations—examples include listings claiming over 70 shapes—while others describe many or seemingly endless configuration possibilities.
For pocket‑size cubes, listed dimensions typically range from about 1.7 × 0.9 × 0.9 inches up to roughly 5.0 × 1.3 × 1.3 inches, with weights commonly around 0.1–0.4 lb. Some larger cube‑style games in listings show bigger dimensions (for example, up to about 7 × 0.75 × 5 inches).
Durability features called out in listings include durable or injection‑molded plastics, covered or strong metal rivets for hinged cubes, tear‑resistant stickers, and internal rare‑earth magnets that resist wear.
Infinity cubes commonly appear in multi‑piece fidget kits, sensory tool assortments, and classroom sensory sets; product listings for these kits often list an infinity cube among the included items.
