[Environmentally and Human-Friendly Building Blocks] These large blocks are made from silica gel, which has the same components as quartz and crystals found in soil. They're over 4.8cm in size, making them difficult to swallow. Even if accidentally ingested, they're excreted without being digested or absorbed. They're also food-safe, meaning they're safe to ingest. They're heat-resistant, so they can be sterilized by boiling. [An Introduction to STEM Education] These blocks were developed to encourage independent learning, self-understanding, and self-discovery from an early age. Thinking about what they can create improves their thinking and concentration. They're great for indoor play, as well as in the bath or pool.
