Lab Boiling Stones, Solid Round Clear Glass Boiling Beads, 5mm Diameter, Approx 1000 Beads

Perfect size for what I needed.

Maybe not the most accurate review since I got these to use for miniature painting (embed them in resin to simulate bubbles, or alien eggs, etc) But they were perfect for my purpose, so 5 stars it is!

I didn't count, but it seems close enough to 1k. Good size and weight for dropping into little paint bottles as an agitator without the risk of rusting. Just find a better container once you have them, I wouldn't trust a plastic bag to contain these things safely. A spill would be very troublesome to pick up.

BE AWARE, they really only send the exact number of glass beads by count. Take that into careful consideration. I ordered the 2mm beads & got less than 1/2tsp. total.

Fits into vallejo droppers.

Little glass balls

These balls are really great for mixing up paint in small bottles.

It definitely helps the boil but the thin package could easily tear during shipment.

My first impression is that these are art the small end of the scale for use with viscous acrylic paint in a small to medium bottle (e.g., 2 oz.), but would about right for lighter acrylic emulsion. I will obtain some 4mm beads for the thicker paint and larger bottles.

Están bien y son funcionales pero son muy pocas por el precio
