Water Blocks

Reviewers across multiple ages report the blocks surviving months of throwing and handling by toddlers with no cracking or seal failure, and repeatedly describe them as sturdy, heavy, and smooth, with only cosmetic color fading from sun exposure noted.

The blocks teach color theory, mathematical thinking, coordination, cause and effect, concentration, and language, but there is no method connecting the physical features to each named skill beyond the basic color-mixing mechanic.

A dated lab report for this exact product confirms it passed ASTM F963-17 mechanical, flammability and heavy-metal requirements along with CPSIA lead and phthalate limits, component by component, with no failures recorded.

The product is labeled 3Yrs+ on the retailer page, while the lab report notes the brand separately requested an 18M+ age test for the EN 71 standard on the same item, leaving the actual age fit between the two documented grades unresolved.

We queried the CPSC recall registry directly across its full corpus and found one PlanToys recall: a 2017 baby gym recalled proactively for a strangulation hazard, with no injuries reported. That recall covers a different product line than these Water Blocks, so it sits outside this product's own history.

These Water Blocks were tested against ASTM F963-17 and EN 71-1/2/3 by a named lab, with a dated report covering heavy metals, phthalates and lead in each component, all passing. The brand cites these standards for its full product range.

The wood is named as rubberwood from trees that no longer produce latex, the glue is identified as non-formaldehyde, and a spare-parts replacement route is offered for missing, broken or defective pieces, though at an unspecified charge rather than free.
