Soon as these came in the post and were opened the little one who is 4 years old wanted to open them and get them out to play with. They are a brilliant size for little hands, around 15cm long. The weight is spot on, not too light and not too heavy. They appear to be durable as they have so far withstanded the sand and water table, the bath, the patio, etc. The markings on each one are appropriate and the little one wanted to know what the name of each was so they do have educational value.
Overall super quality and would definitely buy again. Probably will buy as a present for another child's birthday as long as I knew parents and children would be happy with sharks.
