The universe is full of amazing things

All subscription boxes ship in the first week of each month from our shop in Tulsa, OK.

The cutoff for each month's box is the end of the previous month. (For example, if you signed up between July 1–July 31, your first box will ship in the first week of August.)

All subsequent boxes will also ship in the first week of each month thereafter.

Yes. We currently ship Matter to all 190+ countries that USPS serves. Please note, international orders take a bit longer to reach their destination due to customs clearances. Some of the most common delivery times are:

Canada: 1-2 weeks
UK/GB: 2-3 weeks
Everywhere else: 2-4 weeks

Note: International boxes may occasionally include different items due to legal restrictions.

Yes. You can pause your subscription at any time through your subscription page after logging in to your account. If you have any trouble, you can also shoot us a message and we'll take care of it on our end.

You can also resume a paused subscription the same way.

Note: If you pause after a renewal, your paid box will still ship.

Yes. We're happy to custom tailor a box that will make an unforgettable gift for your employees or clients. Please see this page to start the process.

Your subscription will renew on the same day of the month that you initially subscribed. (For example, if you signed up on February 24, your box will ship in the first week of March, and your subscription will renew on March 24.)

You can choose not to renew at any time from your account.

Our goal is for Matter to be the box that we would love to receive as science-loving adults. But the love of science has no age range and MANY people have told us how much their kids and grandkids look forward to their monthly box of Matter.

Some of the concepts may be a bit difficult for younger kids to grasp, so going through the items together and discussing them could be a valuable experience.

We also recommend parents use their discretion about some items which they may find unsafe for their children (examples: glass items that may break easily, items that may have sharp edges, or items designed to produce a spark or flame.)

Do to the rare nature of some of the items in our box, we occasionally have to cap the maximum number of boxes we ship in a monthly batch. If we reach this cap, you may have to wait until someone unsubscribes in the next month before you can subscribe.

We are very picky about the items we select for our box, but we are also constantly searching for new items for upcoming boxes.

If you know of an interesting material, gizmo, or whatever with interesting scientific properties that you think fits Matter, drop us a link using this form!

If you make a product that you'd like us to consider for an upcoming box, you're invited to contact us using this page about sponsorship options.
