I bought these magnets to hold my daughter then one year old when I cook and be able to keep eye. My daughter two years now and still playing with magnets and sister 5 years too. She began now to name them. This product is an excellent teaching tool for your child assimilates the supplementary vocabulary. Not to mention they are very very very strong as it chewed them constantly and they are still intact. A real achievement. Now I try to hide as tidal and tired to go and get them under the couch or other furniture without success not you cut it. It calls them and slips them into her bag when you leave. I even complete the collection.
