The cubes on this page are intended for crafts. They are not "blocks" or "toys" and some may be unsuitable for children. 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). These are close to the limit for Kiln Dried hardwood lumber and may suffer from some minor flaws. They may require some sanding, smoothing or other finishing for many projects and we do not warrant their use for any particular purpose.
