About matter

MATTER is a passion project from the best science shop in the universe. Everything we do is to promote evidence-based reasoning and inspire the next generation of thinkers. MATTER is for anyone who appreciates the vast scale and variety of our universe and the matter that makes up everything within it.

We ship all boxes on the 4th of every month to everyone subscribed by the end of the previous month. No matter what day you subscribe, your first box will ship on the 4th of the following month. This helps us determine how much product to order. Need something sooner? A past box may be perfect for you. If not, email us and we’ll figure something out. To keep MATTER affordable, we ship using USPS First Class. This means most US subscribers should receive their boxes in 3–5 days.

International: We gladly ship worldwide, but shipping to addresses outside of the US can be expensive and time-consuming. We’ve been able to reduce international shipping to $10 for Canada and $14 everywhere else in the world. Due to the slow nature of customs, please allow 2–3 weeks for your boxes to be delivered outside of the US.

Packaging: We’re happy to say MATTER packaging is 100% recyclable, compostable, and biodegradable. Our outer cardboard box is made from recycled ingredients and our foam inserts are corn-based and completely water-soluble. Throw the foam in the sink or toilet and watch it dissolve away!
