Guidecraft Hollow Wooden Blocks by Guidecraft
The Jr. Hollow Blocks set by Guidecraft is a 16 piece block set constructed using Baltic birch and northern hardwoods. The edges are rounded and surfaces are sanded smooth and round to eliminate any sharp edges, and are splinter-free to protect tender young hands. These blocks are sealed and finished inside and out and like all Guidecraft blocks, these smooth blocks are made to resist dents and dings.
To clean, use mild soap and water on a damp cloth. Do not use window cleaners or cleaning abrasives as they will scratch the surface and could damage the protective coating.
