Green Kid Crafts is the lowest-priced subscription we cover, and it gives you three or four projects a box rather than one. That makes it a genuinely sensible first experiment. It is also craft-led rather than engineering-led, and every material in it is used up the first time - which is where the comparison turns.
What it really comes down to
Cheap per box against cheap per project
Green Kid Crafts wins the headline price easily, at roughly $20 a month against ibrick's higher figure. But it ships consumables: paper, card, plant-based materials, all used once. Twelve months buys you around 40 finished craft projects and nothing you can rebuild. ibrick buys one kit and then unlocks roughly 50 new builds a year from the same parts. On cost per box Green Kid wins; on cost per year of actual engagement, and on what you still own at the end, it is not close.

Choose ibrick if…
- Your child wants to build machines rather than make things
- You want real physics and engineering, not craft with a science theme
- You want something that is still producing new projects in month twelve
- Your child is 9 or older - Green Kid tops out around 10 and skews younger
- You would rather own a kit than a drawer of finished paper projects
Choose Green Kid if…
- You want the lowest possible price to test whether subscriptions land at all
- Your child is 3-6 and craft is genuinely the draw
- The eco credentials matter to you - this is the greenest option we cover
- You want several short activities per delivery rather than one longer build
Our verdict
ibrick. Green Kid Crafts is the better twenty-dollar gamble and the right call if you are testing the water with a young child, and we would not talk anyone out of it at that price. But it is craft with a science label, the materials are gone after one use, and nothing you make moves. ibrick costs more per month and returns several times more over a year - which is the number that actually matters.

Common questions
Is Green Kid Crafts actually STEM?
It is STEAM, with the A doing real work. There is genuine science in the boxes, but the projects are craft-shaped and the depth is closer to a good primary-school activity than to an engineering curriculum.
Which is better value?
Green Kid Crafts on price per month. ibrick on price per project and on what you still own after a year, which is why we score it higher on value for money.
