The Fireboomoon grape ball is a pack of three squishy mesh balls in orange, blue and green. Squeeze one and the mesh bulges out into a bunch of grapes[1]. It’s a desk fidget toy, nothing more, and that’s the point.
Key facts
What is it, and what happens when you squeeze it?
It’s a soft ball wrapped in a mesh net. Squeeze its body and it changes into a grape shape, as the squishy part pushes out through the mesh[1]. Let go and squeeze again.
The listing pitches it simply: feeling stressed, squeeze the ball and get some frustration out[1]. Think of it as something for your hands while your brain waits on CI. It won’t fix the bug.

How big is it, and what’s in the pack?
You get three balls: orange, blue and green[1]. Each one is 2.36 in (6 cm) across, so it sits in a palm[1]. Amazon’s item details also list 6.5 × 4.1 × 2.2 in and 9.6 oz. Those figures cover the listing as a whole, not one ball[1].
Three balls means one for your desk, one for the drawer, and one for the teammate who just broke main.
How do you look after it?
Squeeze it evenly. The listing warns that working the same one or two spots of the mesh over and over can make it break after long use[1]. Keep sharp objects away from it, so no pens or keys mid-squeeze[1].
If it gets grubby, wash it with water or a drop of detergent[1].
Is it safe?
The listing carries a clear warning: do not heat or microwave it, because of a burn hazard. Don’t leave it in a hot car, in direct sun or near a heater. Squishy toys can burst and release a filling that causes burns. Stop using one that’s torn, leaking or sticky[1].
The listing doesn’t give an age range. It’s sold as a geek gadget for your desk, so treat it as one[1].

Final Verdict
Get the Fireboomoon grape ball if you want a cheap, squishy thing to mash while the build runs. You get three, in orange, blue and green[1].
