ZQuintuplian fidget cubes: our review and test

Compared with the rest: four cubes, a pair of foods and eighteen animals

The cubes sit between a pair and a big bag: more pieces than ICONRY, far fewer than DTYDECLE, and a plainer design than either. Nobody buys this pack for characters; it is a block-shaped object you can hand round.

Anyone who would rather build their own can look at the Doodora kit review, and the anti stress squishy comparison lines up the other lots sold under that shelf name.

We tested it: what four cubes and a listing let us check

We tested the pack the way a shopper can before buying: we went through its five photos, compared the cubes with their neighbours and read every bullet against the others. The findings below come from that reading, with no measurement made up.

Four cubes, four colours

The listing promises "four colorful fidget cubes in one package", and the photos show a set of soft blocks in different shades. A pack of four is the product's real strength: one cube can stay at a desk, one go in a bag, and the others be handed out.

A surface described as smooth

The text calls the surface smooth and the use quiet. Those are two claims about feel and sound that only the cubes in hand can confirm, so we note them as listed and give no verdict on them.

A size line that does not fit

The specification reads 10 x 10 x 0.5 cm. Half a centimetre of depth describes a flat tile, not a cube, and the bullets speak of a size that fits pockets. Most likely the figure belongs to the packaging; the real dimensions are on the box.

Everything in the middle column is the seller's wording. It is useful for comparing lots, not as a measurement taken outside the listing.

Where a fidget cube sits among squishy types

In practice the pack belongs with the fidget blocks sold on the anti-stress shelf: simple, uniform, and meant to be pressed without looking at them.

What the listing never names: the material and the filling

"High-quality material" tells you nothing about what the cubes are made of. That matters because squishies fall into two families: solid foam or rubber, and a soft shell holding gel, liquid, beads or sand.

• Germany's Verbraucherzentrale (7 October 2026) lists the risks as a split shell, swallowed beads, burns from heat and a shell that bursts.
• Stiftung Warentest (26 September 2026) advises against sand-filled models and warns about water beads, which can block the gut if swallowed.
• The UK's OPSS (10 August 2026) reported a coloured cube filled with liquid and glitter, with no identification and no UKCA or CE marking: the liquid was over the permitted microbial limit.
• A Bavarian lab study from 2019 found one foam squishy out of 18 containing dimethylformamide, a solvent with an unpleasant smell.

None of this describes the ZQuintuplian cubes. It explains why a listing that skips the filling asks the buyer to do the checking, and it is the main reason this review caps the safety information score.

What to check before you give them to anyone

A CE mark alone does not settle things: some products named in the German alerts carried one. Read the marking together with the other items, never by itself, and note that the guide to whether squishies are safe goes through the same steps.

Realistic use: desk, bag, goody bag

On a desk

A cube is a sensible object to turn over during a call or while reading. The listing calls it quiet, which would suit a shared office, but every sound claim is untested until it reaches you.

In a bag or pocket

Four loose cubes can shift around at the bottom of a bag, so keep them in a pouch of their own. The listing mentions no case or pouch.

As prizes and party favours

Classroom prizes and party bags are what the seller suggests. A pack of four is sized for that, but the minimum age on the box decides who may receive one. For other ideas, see the squishy gift ideas.

The limits worth knowing

• The material is unnamed, so cleaning and storage advice cannot be taken from the page.
• The size is contradictory: 10 cm wide and 0.5 cm deep does not describe a cube.
• "Retain their shape after repeated squeezing" is a promise, with no figure behind it.
• No cleaning instructions are given.
• Colours are mixed, so you cannot pick which shades arrive.

Who the cubes suit, and who should look elsewhere

A good match if

• You want several matching cubes to hand out or scatter around.
• You are happy to check the box for age, marking and address on arrival.
• You prefer a plain block to a character.

Look elsewhere if

• You want a named material before ordering: the anti stress comparison has lots that name theirs.
• You need a slow rising foam with a stated rise time.
• The cubes are for a child under three, where the Verbraucherzentrale advises against squishies altogether.

Our verdict: 6.5 out of 10

6.5/10 for a simple pack that is easy to like and hard to vouch for from the page. If the box shows an age, a UKCA or CE mark and an address, the cubes make a tidy set to share; if it shows none of them, pick a lot with a fuller listing.
