Magnetic block set! This toy has been VERY popular with my OT kids! It reminds them of minecraft and encourages creativity. This is a mini travel set which can feel limiting for some children. The magnets are very strong and the small size is really great for fine motor manipulation. I purchased this set from Amazon but I have recently sent lots of FB advertisements for similar products. This would make a great stocking stuffer for Christmas or you may want a bigger set. 35PCS Mini Magnetic Bloc
