Haulong Toys Pipe Blocks XL | Large Interlocking Building Set

The larger-sized version of Haulong’s interlocking pipe block system, built for constructing bigger, more ambitious structures than the standard size allows. Blocks connect firmly without being difficult to pull apart, which matters when a child wants to rebuild rather than start entirely from scratch each time.

If smaller pieces suit your child’s hands better, the Small size is the same system at a more compact scale. See more in building blocks and sets.
