Was looking for something to occupy my 5yo while on a recent 4+hr plane trip. Read some reviews of other Sticky Mosaic sets and some mentioned that they were good for travel. Well, I 100% agree. My daughter loved the Princess set and especially the jewel mosaics. It defintitely served it's purpose and occupied her for a couple hours on both legs of our trip. No mess either, each color of mosaic comes on it's own sheet, so we just brought one color sheet out at a time to keep everything organized. And for space saving I transfered everything from the box to a gallon size ziplock, which made it thin enough to fit in her carry-on. The only warning I would mention is that the mosaics stick very well, so tell your child to be careful when separating the mosaics from the sheet because if two get stuck together they will not come apart and are unusable.
