Customer Questions (3)
Q: Do you have new info cards from the earlier editions? I really like how the newer cards have an image and explanation instead of just the smaller black and white info cards.Asked by Amy C., December 2022
We do have new cards for some of the older items. You can email us at support @ stemcelltulsa. com - let us know which cards you need and I'll see what I can send you! Thanks
Q: Are boxes always different or do they repeat? Thinking of renewing a third time and want to make sure it's not the same box. Asked by Phoebe B., May 2021
The items are new every month.
Q: Would this be appropriate for a curious 10yo? My son loves to examine, touch, explore. I know he would love the items but is he old enough to appreciate it fully? Thanks a loving MomAsked by Kim M., December 2019
Hi Kim,
We curate our boxes so most items are suitable/understandable for most ages (i.e. prehistoric fossils, interesting trinkets, minerals, activities, etc.) But as you said, some items may be difficult for kids to appreciate (i.e. aerogel—the lightest solid material humans have ever created—as well as pure element samples). For this reason, we include informative cards that can help adults explain the significance and provide a starting point for further research.

Probably one of my favorite subscription boxes EVER! If you have kids and they love knowledge and seek out information constantly, this box is an education easter egg that initiates the start of great conversation and exciting exploration into learning. My daughter loved it and my husband and I were kind of jealous, but in a good way.
Sooo cool!

This has been a gift for my 10 year old grandson who can be hard to shop for. This is perfect for kids (and adults) who fall into the category of not falling for the humdrum. My daughter (the mom) probably loves it as much, if not more, than he does.
Too expensive

Shared birthday present this year; 12 interesting surprises. Arrived safely. We tried to postpone opening till the weekend, but curiosity would not allow for further delay. We might do better next time?! Expectations were satisfied. Impressed with the quality & detail. Looking forward to the next… Thank You, The Stemcell shop! X

This is such a fun box! I’m not even a super sciency person, but love to learn about the different things that come. And it’s going to make for an amazing collection of items!

partner and i look forward to the next month! both of us being science geeks, it’s a great little reward for both of us.

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!
