Using the Stanley Jr. 40 - piece pretend play toolset is super easy. Let your kids pick the tool they need for their pretend construction projects, like using the wrenches to 'tighten' or the screwdrivers to 'fix'. As for safety, make sure kids don't use the tools roughly or throw them around. Keep small parts out of reach of kids under 3. When it comes to maintenance, just wipe the tools with a dry cloth after play to keep them clean. This will ensure they stay in good shape for long - lasting play.
