Review on Big PLUS PLUS Open Play Tube - 15 Piece Pastel Color Mix - STEM/STEAM Construction Building Toy for Toddlers and Preschoolers - Interlocking Large Puzzle Blocks by Heather Shaw

Who knew? This is a great recommendation so I'm glad I bought two sets for both kids. They played with them many times during the trip. I removed them and they pulled them out again. They're small, so they fit in the toy fridge we locked between the car seats. Both children could access their plus points whenever they wanted. Def is part of staying in the car arsenal. Perfect for long journeys or even long waits when they need a toy that won't be a bad missile in the event of an accident or sudden stop.
