*by M***9 on 9 July 2020*

I’m very pleased with this purchase. My son wanted a dinosaur themed birthday so I got these to hide in a sandpit and made a Dino dig. He loved the idea and it was an extra present. I love what they’re made from and they’ll be great for younger children and older ones alike. Perfect for what I wanted.
