Purchased for my nearly 4 year old & he absolutely loves it. I think this is a great buy for the price your get so many different items to use. The kit contains a whistle, compass, 3 collection jars (2 with a magnifier), a small catch net, a large magnifying glass, binoculars, a set of insects, tweezers, a set of scissor collectors and a bag to keep everything in. The products are all good quality as well. Really pleased with this buy and would definitely purchase again - would make a great gift just so many different nature activities can be explored with this kit. It states for 3 years or older which is probably about right, the only smaller items are the bugs though. Great buy !!
