Frequently Asked Questions

Q: Are these building block keychains compatible with LEGO bricks?

A: Yes! The 2x4 MOC building blocks in this set use standard stud dimensions that are compatible with most major brick-building brands, including LEGO. You can mix and match with bricks you already own to create unique keychain designs.

Q: How many keychains can I make with the 16-piece set?

A: The number of keychains depends on your design. A simple 2x4 single-brick keychain uses just one brick plus a loop chain connector, so you could create multiple individual keychains. Alternatively, combine bricks to make one larger, more detailed keychain design.

Q: Is this set safe for children?

A: The bricks are made from durable ABS plastic with smooth edges and non-toxic materials, making them safe for children. However, adult supervision is recommended for children under 3 years old due to the small parts that could pose a choking hazard.

Q: What does the set include?

A: The set includes 16 ABS plastic 2x4 building bricks along with loop chain connectors, giving you everything you need to assemble and attach your custom brick keychain right away — no additional tools or accessories required.
