    What People Are Saying

    Great for making telescopes!

  • These were used to make telescopes in our preschool camp. The kids loved them and were very excited to learn how the lenses worked. I appreciated that they were individually wrapped although it would be nice if they were all labeled individually. About a third of them were unlabeled. The price was great too.
