The cubes on this page are intended for crafts. They are not "blocks" or "toys" and some may be unsuitable for children due to size. They may be Maple, Birch, Poplar, Alder or a mix of these. They have crisp corners and edges (they are not chamfered or rounded on the edges). We typically send about 3% extra but customers should anticipate some defective cubes and compensate accordingly when requiring specific numbers. The smaller sizes are weighed, not counted, and amounts may vary from the number ordered but will always be in excess. They may require some sanding, smoothing or other finishing for many projects and we do not warrant their use for any particular purpose.
