For ages 12 and up. For anyone, really.

This is where it all started. The Original Cube is a precision-cast acrylic cube made in cyan, magenta, and yellow, the three primary colours of light subtraction. Hold it up to the light and the colours pass through and pool on the surface below, mixing and shifting as you move it. Overlap two faces and you get a secondary colour. Line all three up and you get something closer to brown or orange.

It sounds simple. The experience is not.

There is something almost hypnotic about the way light moves through the cube. The colours are richer and more saturated than anything you would see in a paint set or a screen. The overlaps are clean and precise. And the moment a child figures out that they are seeing colour mixing happen in real light, not pigment, tends to land with the kind of quiet surprise that makes a genuinely good toy.

The Original Cube comes in three sizes: Mini, Original, and Mega. The Original is the sweet spot for most people, large enough to see clearly, small enough to carry around and hold up to any light source you find interesting. The Mini is a great option for younger children or as a stocking filler alongside something else in the range.

It has over 850 reviews and a 4.9 star rating. That is not a number that happens by accident.

Who it is for: the kid who asks why the sky is blue. The one who holds everything up to the window. The one who is never quite satisfied with a simple answer.

PRISM Pencils bring the CMY Cubes colour philosophy into the art space. These are not ordinary coloured pencils. Each pencil contains pigments that blend and shift as you draw.

The effect is striking. A single stroke can move from one hue to another mid-line. Layer two PRISM Pencils and the colours interact in ways that feel almost alive on the page. It is colour theory made tactile, and it rewards the kind of patient, exploratory drawing that is genuinely good for developing minds.

PRISM Pencils are the ideal gift for children who sit somewhere between science and art, or who have not yet discovered that those two things are not really separate. They are also a beautiful companion to the Original Cube: use the cube to understand how colours combine in light, then pick up the pencils to explore how the same principles play out in pigment.

Who it is for: the kid (or adult!!) who fills sketchbooks. The one who mixes paint colours just to see what happens. The one who loves art but would secretly enjoy knowing the science behind it.

For ages 3 and up and every age beyond that. For the collector, the squeezer, and the geometry enthusiast.

The PolySquish is a mystery box, and that alone is most of the appeal.

Inside each box is one squishy polyhedron: a Tetrahedron, Octahedron, Dodecahedron, or Icosahedron. Each one has a vibrant outer shell colour and a surprise core colour revealed when you squeeze it. There are 16 unique shape and colour combinations to collect, including four secret rare variants.

The squish itself is genuinely satisfying. The interior resists slow pressure but yields quickly to a fast squeeze, then springs back to its precise geometric form instantly. It is the kind of object that is impossible to leave on a table without picking it up. Adults included.

Beyond the sensory appeal, each PolySquish is a geometry lesson in disguise. Children who collect them start to notice the differences between shapes, to count faces and edges, to ask why some polyhedra look rounder than others. The dodecahedron in particular tends to stop people in their tracks. Twelve pentagonal faces, perfectly symmetrical, a shape that looks like it should not work but does.

CMY Cubes’ PolySquish is also the most accessible entry point into the CMY Cubes range, and the collectible format makes it endlessly repeatable as a gift. One for a birthday, another for a holiday, a third for no reason at all. They stack, they display beautifully, and they are genuinely hard to stop collecting.

Who it is for: the kid who cannot stop fidgeting. The one who needs something in their hands while they think. The one who will spend an hour trying to find the rare ones.

Most science toys explain things at you. They come with booklets, demonstrations, pre-set experiments. They tell you what to discover.

CMY Cubes work differently. They put something genuinely interesting in your hands and let the curiosity do the work. The questions come from the child, not from the instructions. Why is that colour coming out there? What happens if I overlap these two? What is inside this one?

That mode of learning, open-ended, physically driven, led by genuine surprise, is also the most effective kind. Children who discover something for themselves remember it. They want to show it to other people. They ask the next question.

The best science gifts do not feel like science. They feel like play. And then, a few minutes in, you realise you have learned something.

That is exactly what CMY Cubes are designed to do.
