These are great and are a lot of fun for kids, but I do wish Grimm's had made them a bit larger so none were a choking hazard. These would really be perfect for younger kids if not for the small size.
A great, versatile set—both for strategic learning and open-ended play! As with many of the natural (non-stained) pieces in Grimm’s toy line, I might recommend opening upon arrival so as to let the natural oil scent* dissipate.
*In case it lends any added peace of mind regarding the scent, per Grimm’s manufacturing website: “ […Grimm’s oils their] wood products with a mix of different natural oils with linseed oil as the main ingredient. This blend consists of linseed oil, olive oil, thistle oil, walnut oil and soybean oil. […] The stronger smell is typical for natural linseed oil which is completely harmless, and it will decrease over time.”
