I purchased three-month gift subscriptions for both my mother and mother-in-law this year, and they really enjoyed them! (In fact, this has become my MIL's default gift for HER friends; I know she's purchased a few subscriptions.) The items are well-made and lovely, and you can't argue with the mission behind this one. Would definitely recommend.
I purchased a three-month subscription for my father - a dedicated science, history and overall knowledge junkie - earlier this year, and he loved it. The items were excellently curated (and now housed in a display case on his wall) and well-packaged, and just really, really cool. I would absolutely recommend this box to any-/every-one.
