The big one. Properly big.
Gump Jumbo is the same memory gel stress ball as the original, scaled up to 10.1cm — which sounds like a small change and absolutely is not. At this size it stops being a palm toy and becomes a two-handed one. You can't close a hand around it, so instead you press into it with both thumbs, and because there's so much more gel inside, it oozes back far more slowly. The whole thing is calmer and more deliberate than the original.
It's the same construction: a velvety thermoplastic rubber shell over a slow maltose gel core, fully sealed, with nothing to spill and nothing sticky left on your hands. The extra volume also means more resistance, which is the bit people who find the standard Gump too easy are actually after.
Six translucent colourways — Dew, Sea Glass, Moon Jelly, Algae, Reef and Mist — the same palette as the original, so a Jumbo and a standard in matching colours look deliberate on a desk rather than accidental.
This is the one that stops people in the shop, because the size is genuinely surprising when you pick it up. Come and get both hands on one at 22 Burgate in Canterbury — it's not a thing a photograph can convey. Order online for UK delivery.

FAQ
Is this a genuine Speks product?
Yes — Wrapped! is an official stockist.
How much bigger is Jumbo than the standard Gump?
10.1cm across against roughly 6cm, so a little under twice the diameter and around four times the volume. It's a noticeably different object, not just a size up.
Does it feel different to squeeze?
Yes. More gel means more resistance and a slower return to shape. The original is quick and springy; the Jumbo is slow and heavy. People who find the standard one too easy usually prefer this.
Can I use it one-handed?
Not really — it's too large to close a hand around. It's designed to be worked with both hands or pressed against a desk.
What's inside it?
A soft maltose memory gel, sealed inside a flexible TPR shell. It won't leak in normal use.
Can I wash it?
Don't submerge it long-term, but if the surface gets sticky with use: wash with soap and water, let it dry completely, then dust lightly with cornflour to restore the velvety feel.
Which colour will I get?
The colour you choose — each is sold individually, not assorted.
Is it a good gift?
Better than the standard Gump for gifting, because the size makes it feel like a real present rather than a stocking filler. It's also the one that gets picked up by everyone who walks past the desk it lives on.
Safety
Recommended for ages 14+.
WARNING: NOT SUITABLE FOR CHILDREN UNDER 3 YEARS. SMALL PARTS — CHOKING HAZARD.
- This is a stress-relief and sensory tool rather than a children's toy. We recommend it for ages 14 and over; younger users should be supervised by an adult.
- Not for anyone who may bite, chew or suck it. The gel contents are not for ingestion.
- Check it before each use. If the outer shell leaks, splits or ruptures, stop using it and dispose of it immediately.
- Avoid very aggressive stretching, and keep away from sharp objects, pet teeth and direct heat.
- Squishy gel toys don't last forever — lifespan depends on how hard it's used.
- Keep packaging away from children.
