Stainless steel mixing balls in 316L grade, sized at 5.5 mm to fit the standard 17 ml dropper bottles from Vallejo, Scale75, Army Painter and AK Interactive. Drop one or two into a bottle and shake — the ball breaks up pigment that settles to the bottom and brings the paint back to an even consistency. 316L is alloyed with molybdenum for strong resistance to acids, solvents and salts in hobby paints, so it will not corrode inside the bottle. Steel is denser than glass, which means more energy per shake and faster mixing.
316L grade — acid-resistant, corrosion-resistant and safe for long-term contact with paint.
5.5 mm diameter fits 17 ml dropper bottles from most hobby paint brands.
Heavier than glass agitators, so they break up settled pigment more effectively.
Available in packs of 10, 25, 50 or 100.

Notes · Q & A
Sprue cutters or a hobby knife — what do I actually need?+
Cutters remove parts from the sprue cleanly; the knife trims the leftover nub and mould lines. You'll want both — they do different jobs.
What's the difference between single-blade and double-blade cutters?+
Single-blade cutters shear against a flat anvil for an ultra-clean cut with less stress on the plastic; double-blade cutters are tougher for general work.
How do I keep tools in good condition?+
Cut plastic only (never metal sprues or wire) with precision cutters, replace knife blades often, and keep files clear with a brass brush.

How can you review a product when you didn't receive it. Express post it said, 9 December it's now 18th
Thank you for your review. You placed your order on December 9th, and today is only December 12th. Considering your location on a remote Scottish island, combined with the holiday rush, expecting delivery within such a short timeframe is unrealistic.
What’s more, you didn’t contact us about this issue at all before leaving this review. We are always happy to help resolve any concerns, but reviews like this, without proper context or communication, feel unfair and disconnected from the realities of holiday logistics.
We kindly ask for a bit more patience during this exceptionally busy season.

Great load of balls
What I needed, at a good price and speedily delivered.
They seem to be doing the job well, helping with the mixing and revitalising of my (expensive) Citadel paints. Makes the whole thing more sustainable, too, as I am not having to throw out so much dead paint. May not help GW's profits, but my pocket money is going further.
