I have to confess that this is the first time I see these cubes and they are really fantastic I think they have a great potential for the development of vocabulary, mathematical logical thinking, creativity, concentration and many more cognitive processes, really the cost was very economical for the amount of hours that children can spend learning in a fun way which is wonderful. Many congratulations for the choice of educational toys for your children those are for life, I still play with my alphabet soup, well I already use the scrabble and my family and I have a lot of fun with it in this pandemic has been very helpful especially when the power fails, which in my country is quite frequent. Thank you very much today I have learned something new with your post.
