The fix for gummy, separated hobby paint: drop two of these 5.5mm stainless steel agitator balls into any paint bottle and a 30-second shake mixes pigment and medium back into a smooth, ready-to-use consistency. You get 100 balls — enough to upgrade an entire paint collection — and because they're high-grade rustproof stainless steel, they'll never corrode or discolor your paint.
Pair them with the Speedpaint Starter Set 2.0 or a set of Paint Mixing Empty Bottles, or browse our Scenery and Figures & Vehicles collections for things to paint.
How many balls should I use per bottle?
Two per bottle is the sweet spot — they move randomly against each other when shaken, which mixes better than a single larger ball.
Will they rust in water-based paint?
No. These are high-grade stainless steel, so they won't rust or tint your paint even after years sitting in the bottle.
Do they fit dropper bottles?
Yes — at 5.5 mm they drop right through the neck of standard 12–18ml dropper bottles from The Army Painter, Vallejo, AK, and similar.
Do Speedpaint 2.0 bottles need them?
No — Speedpaint 2.0 bottles come pre-loaded with two mixing balls. This pack is for the rest of your collection: older paints, washes, metallics, and any brand that ships without agitators.
