I'm not overstating it when I tell you my daughter was THRILLED with the concept of receiving abox filled with fun science and brainiac materials (including a BOOK--she adores books). She thanked me repeatedly (which was awesome too) but her continued interest in the materials beyond the first 5 minutes was the big thank-you. Her older brother also found the book fun to read. This one was a winner! The box arrived in good condition too and the presentation with a little tissue made it a genuine gift. Thanks again!!
