Lab Safety Tested
Safety tested to EN 71, the toy safety standard used across the UK and Europe.
Our sets were checked by an independent testing lab for children aged 3 and up: sharp edges and points, magnet strength and how securely the magnets are held, flammability, and lead and other metals in the plastic and colour coating.
They passed every test, so you can hand it over with total peace of mind.
From nursery pick-up to dinner on the table… some days feel endless.
Parenting is hard. They come home from nursery wanting all of you, and dinner still needs making. The hour before tea is the longest of the day.
The tablet is the only thing that buys you peace — and the guilt lands the moment it's switched off.
You just need twenty minutes to get dinner on the table without a small person at your knee. You're not alone.
Stop choosing between a meltdown and a screen.
You want 20 minutes of quiet, and the screen delivers it — right up until you take it away. Offscreen Play is different.
It's the pause button parenting actually needs, minus the guilt. It isn't a distraction. While you get dinner on, they're working: stacking, balancing, working out what holds the cave up, and starting again when it doesn't.
Finally, a toy that buys you time — and dad can't put down.
Something happens when Dad walks past a half-built cave. He picks up one cube to help, and twenty minutes later he's the one working out how to span the gap without the roof coming down.
The magnets pull together hard enough that grown-up hands want a go — so it stops being a toy you supervise from the doorway and starts being the thing you build together.

Photo reviewSuper cool magnetic blocks that are well-made and hold together securely. You can hear the small magnets inside when you shake them. I would order two sets for larger "building projects." We were very satisfied.
