I always loved these glow stars and it is important that they are good quality to avoid disappointments. My 11-year old son was commissioned with decorating his toddler sister's room and did a masterful job: he had fun and she can wake up at night and be inside a constellation. And even though he filled her room, he still had enough left to constellate his own den under the stairs. They're brilliant, shiny, and mystical. My partner even recreated actual constellations with them a few years ago. I really recommend this product.
