“These are great! Was really impressed with the way everything is set out, each experiment in separate labelled bags, making it very easy to find what you need. Knowing you don’t have a dash to the supermarket to buy extra ingredients is fantastic too. It’s also aligned to the curriculum and key stages so perfect for home education.”

What our customers say…
“We love Letterbox Lab, we have tried a few of the others that are out there but letterbox lab is definitely the best! We subscribe to this for my 5 year old but find that her older siblings join in too. Love it! “

“Letterbox Lab is truly exceptional – my son absolutely loves it. We homeschool, and this is the best educational subscription box I’ve found. The experiments are so much fun, and there’s a definite progression through each month’s theme as you follow the experiments. This is a box that takes science education seriously and doesn’t condescend to, or underestimate children’s ability to understand scientific principles. My son has learned so much from Letterbox Lab – I couldn’t be happier!”
