This is really one of the best subscription boxes I've ever had. My kids and I look forward to it arriving so we can add everything to our growing collection and read about all the unique items. You never know what you're going to get but it's all going to be exciting to learn about, handle, and use. It's like getting your own little museum exhibit delivered every month (but none of it's behind glass!). So glad I found out about Stemcell; it's my new go to shop for gifts for my science loving family!
