What size are diamond art drills?

In our kits, round drills measure 2.8 mm and square drills 2.5 mm. They are small faceted resin pieces with a flat back so they grip the glue.

Each square on the canvas takes one drill, so a 30 × 40 cm canvas needs about 15,000 (round) to 19,000 (square), supplied in bags sorted by colour. To choose between the two shapes, see our round or square comparison.
