Adult Blocks
 
They're little boxes actually... individually crafted from OSB - oriented strand board - a common, efficient, and banal construction material.  OSB is not intended for exposed surfaces - it's simply rough finished, glued and compressed wood chips.  However, they create a lovely and variegated natural pattern! Accent that with color and craft them into cute and fun, handleable cubes and blocks.
 
Blocks are smooth and sealed with a water based, low voc, matte finish. Intended for display, accent, fidget, play, and fun!  Not to be chewed, but please stack and play...
