- Mystery Matter Box














I bought 2 boxes together vice the subscription and was thrilled to see there weren't duplicate items. Dad was happy with his new trinkets and fun facts.
A wonderful purchase and a great gift for any science lover.
My brother loves science and he absolutely loved these boxes. I bought two of them and both had different items and cards explaining what each thing was
Fun packaging, good variety, loved the info cards!
We ordered a mystery box but specified it was for a boy who is obsessed with the periodic table and the elements and we received a box with all elements in it! It is amazing and I'm sure he will absolutely love it.
I got several neat things. The thing I found most interesting is the Menilite sample. I intend on using it for an experiment in my college Mineralogy course using an electron microscope just to see what that might look like.
I got this as a birthday present for my brother and he loved it! Thanks for creating such a creative and interesting gift.
The mystery box was an amazing glimpse into what this company offers. The information cards are terrific and the quality of everything was superb. My teen is rarely impressed; he certainly was about this box.
Ordered as an anniversary gift for my husband. He was very excited about the items included in the box. The cards describing the items were very useful and informative.
Amazing subscription box that teases the scientific mind. Unique items in each box that make it feel like a holiday every month. Conversation starters for the whole family!
