Bauspiel 窺視孔積木

The colored lenses inside each block create surprising new hues when you look through them, which my toddler finds endlessly fascinating. We've built small towers just to peer through the different windows at different angles.

My toddler loves stacking these blocks and peeking through the colorful holes—the different shapes make each tower a little surprise. They're solid enough to build up pretty high without toppling.

The colorful geometric shapes on these blocks catch the light beautifully as my child builds. They're a bit smaller than I expected, but they stack very stably and my little one hasn't gotten bored of them yet.
