This has been great for storing and playing with DUPLOs. My 3&4 year old can move the bag anywhere in the house, open it up, find any DUPLO they want to build without needing to dump it all on the ground! I’m so excited to have found a better storage solution for this season of our lives! Now I’m tempted to get more - one for legos, one for brining toys to grandma and grandpas, maybe some small ones to bring toys to restaurants or when we travel?! Thank you for inventing such a fantastic product...
