Letterbox Lab is like a science magazine, science kit and science club all rolled into one. You can subscribe to them so they arrive automatically through your letterbox every month. Each box contains a whole bunch of activities, experiments and creative projects that engage your child with science for hours on end. We send you everything you need to play with science – no extra materials needed (except the occasional household item like water or a slice of bread).

1. Choose between the Explore box or the Investigate box.
2. Choose if you want to pay monthly, pay every 3 months, 6 months or buy the entire 12 box series!
3. Every month you get a box of awesome science experiments through your letterbox.

All orders are shipped within three working days by Royal Mail 48. When you start a subscription your first box will be added to our next shipment, so you’ll get it within a week. If you want to know when our next shipping day is just ask.

Some customers like the first box in the subscription to be delayed so that it arrives close to a special day. If you would like us to aim for a certain date please just let us know in the notes section of the checkout – we will do our best to make it happen!
