Bebe the Tape Measure and the Safety Glasses are designed for ages 3+, while Wammy the Hammer is recommended for ages 5+. Together, they make a great set for builders 5 and up, or for siblings who can share and grow into each tool.

Between ages 5-6, children are ready to develop and refine fine motor skills and hand-eye coordination. Each measurement, each hammer swing, and each project strengthens these foundational abilities. At this age they can follow multi-step instructions and understand cause-and-effect. By ages 7-9, kids enter the Concrete Operational Stage where logical thinking develops. With real tools in hand, they're building on those coordination skills while developing problem-solving, planning, and precision. They'll understand why accuracy matters, troubleshoot independently, and begin to grasp how measuring and building work together. This bundle grows with your builder through each stage, turning play into meaningful skill development.

ASTM-F963 is the safety standard for children's products. It tests for edge safety, material safety, durability, and to make sure there are no hazardous materials. These tools pass all tests for safe use by children 3+ and 5+
