Here's the thing, when it comes to finding toys that your kids will love for years to come (we're talking light years) it can be tricky. What a child loves at six they may ignore at eleven. Which is why we were so excited to find the A4 Lightbox. The Lightbox continues to be loved by children and parents (and even teens) with their ever-growing letter sets! This particular set is full of monochrome letters and symbols, perfect for the coolest of kid's room. Because even though our kids grow up, the fun never has to stop!
