Fun design and theme

[This review was collected as part of a promotion.] My 4 year old absolutely loved these. She already had a set of just plain colors of red, blue, purple, yellow and green. When she got these she was filled with joy. She loved the theme with the fishies that came in the set. I would recommend these magnet tiles for anyone looking to get something fun for their Littles to do.

A fun themed set that sparks hours of creative play for different aged kids

[This review was collected as part of a promotion.] We absolutely love this MAGNA TILES coral reef set! We already own other set from MAGNA TILES, and this is a great addition to our collection. The coral reef themed pieces add fun ocean play to their imagination, and the soft touch items are a bonus. The set is super light and easy to clean up for younger kids as well. My kids, ranging in ages from 2-7, all enjoyed playing with it together, which doesn't happen with many toys. The pieces are all the right size, well made, easy to connect, and fully compatible with the other existing sets, which makes setup simple and easy. I also thought the packaging was great, as all the pieces were still secure in place when we opened the box. If your family already has MAGNA TILES or your just getting started, this is a fantastic set that encourages creativity, open-ended play, and keeps kids engaged for a long time.
