Such a brilliant nesting toys for babies

I found this great circle pipe at art shop, untill now i do not know what it is actually for but I bought them because I figure it would serve as a very easy nesting toys for her.

So as can be seen its a cylinder shape which opens up at both sides means an easy work for really really young toddler like Diha.

See how Diha just take them up and shove them in , since its open end at both sides it makes it easy to stack?

The increasing size is good motor practice for her fingers.
