I was honestly surprised when I received my toy set. I wasn’t expecting such an extravagant set. I’m really impressed with the storage case along with the durability of the magnetic pieces. The tiles are about .25″ thick. They are colored yet transparent which I love. The magnets are extremely strong. You don’t have to force them to stick together at all. This does make it tricky sometimes when you are building something large. When the pieces get close together, they will strongly attach to each other. This does make it simple when cleaning up though. They stack perfectly inside the storage case with some room to spare. Kids will spends hours playing with this and adults will even love to join. It makes a nice toy for siblings, friends, and family to play with together. I definitely think this makes a great gift option for many occasions such as birthdays and Christmas or simply just because you want to make some child happy.
