Here at The Foundry we know that if you want something done right, you have to do it yourself. Or, in the case of our marvelous Handmade Maple Baby Blocks, you have to enlist the help of your brilliant shop-neighbor who just so happens to be a master carpenter, woodcraft genius, and maverick innovator of the old school. Custom crafted in Minneapolis just for us, and commissioned exactly to our babe-tested-specifications, each of these perfectly minimal teether toys is hand-milled from a single piece of hard, straight-grained maple wood. Babes can't resist the smooth-as-silk rounded edges, spatial-relations contrasting logic puzzle, and the mouth-and-finger-friendly-contours. And, unlike basically everything else in the modern-babe-age, this makes no noises, requires no batteries, and looks right at home sitting on top of your copy of "Noguchi's Imaginary Landscapes". Can't say that about Sophie.
Note: While our XL cube is just as great for "putting in mouth", "waving in air", and "banging on stuff" as the other sizes, the 8" size is also a great help in those wobbly transition periods between lying/sitting and sitting/standing.
