Our beautiful new River Pebbles Wooden Blocks from Grimm's Spiel & Holz of Germany are shaped to resemble smooth river stones. They're perfect for balancing and stacking challenges, decorating scenic play, making a stony puppet show landscape, and building cairns. Each four-piece set comes in your choice of one of five color schemes: River (Blue/Gray) Fire (Red/Orange) Moss (Green/Yellow) Flamingo (Pink/Red) Dream (Purple/Blue) These unique blocks are the perfect companion to our Colored Wooden Gem Blocks! Variations in wood grain, color, knots, texture or dye transfer are all natural occurrences in these hand-stained wood products.
