WHAT IS MATTER
Matter is our monthly subscription box. It is currently one of the top science boxes available. Most months we have extra items and we offer a random assortment of these items here to anyone who may be curious about what to expect in the subscription.
Please note: This listing is for a one-time box of an assortment of items and NOT a subscription. If you're interested in subscribing to Matter to get new, fresh items shipped to your door every month, you can find out more here.
