Grimm's Basic Building Set 1

Our toddler loves figuring out how the curved pieces create a little tunnel for toy cars. The angles and straights are just the right size for small hands to grip and stack without toppling too easily.

The triangular and curved pieces fit together perfectly, creating a surprisingly sturdy little village that has held up for hours of play. My toddler is genuinely engaged with the different angles and shapes.

My son is usually hard to impress, but he spent a solid hour building different structures with the angled and curved blocks. The triangular pieces add a nice challenge that flat blocks just don't offer.
