In the images, it looks like it's compatible with Duplo, but it's another version of Lego that's smaller.
Received quickly 👍

Great product, I recommend this seller.

I cannot give this to my three-year-old grandson because the pieces are very small. Not suitable for minors!!!! This is for adults.

The quality is good, but the fit is poor. I took size 130 for my son and it barely fits him; you need to take at least two sizes larger.

Unfortunately, the base arrived broken but I will fix it with some Scotch tape underneath.

Delivered quickly. Looks like pretty good quality. I recommend it.
