This silicone mold makesa 30mm (1-1/8")round balls/spheres! It's made to pour resin into and let set, creating round 3D beads.

Bead size:30mm (1-1/8")

Note - the mold is in two parts, which will need to fit together before you pour the resin through the hole in the top part. Make sure the lip of the two halves fits in place all the way around to seal the mold shut! See thethird picture for the fitted pieces. May require a small amount of sanding at the connection point.
