I ordered these by mistake -- somehow I thought I was getting size 0/ 2mm (which is what most of our jewelry kits are knit with) and I actually ordered size 4 (3.5mm).

Oh well.  They are still very fine needles.

Here is what Knitter's Pride says:  Cubics are perfect for beginners, and a must-have for experienced knitters. Cubics have a square shape that fits and feels wonderful in your hands. Their unique ergonomic shape provides comfort to keep you knitting longer. Made from a durable laminated birch wood with a rich rosewood color that brings out the natural beauty of the wood grain.

These are single pointed needles, 10" long.
