Doesn't every mature woman want to step back and wonder what it would be like.  Romantic characters. I want more and now I see there is more available, Cade had brothers. This author has left many windows open.

Great toy for youngsters - open to their own imagination.

Bought them for our grandson who spends a great deal of time using his imagination to make all sorts of creatures and objects.  The blocks are fun, not only because they actually stick together better than traditional blocks, but the many different shapes allow a child to be more creative.

I bought a couple of these sets for my friend's children. They seem to like them and have made some interesting contraptions. These K'nex sets are pretty easy to put together with single connectors...each piece connects to others with one snap. These are different from Legos actually appearing more realistic. One draw back is the pieces are more fragile (breakable) and may need adult help with younger children.

Overall, I (er, the kids) find these to be fun and even educational...A newfangled idea for youngsters.

We made this together a few days ago and had a lot of fun. Comes with a few extra pieces in case some get lost, and all the pieces fit together well. Might be a little complicated for a younger child. But still fun for grownups :)

I got these for my 6 year old and she loves them. I love toys that a child can use there imagination and mind to build things. It keeps her entertained for a long time building different things. i would recommend buying a container to store the pieces in.

This is a great story for children aged 2 to 5 years old. The story line is very cute and imaginative.  It reminds me of the many times my daughter and I played with a box. I think you should have a box handy after the story to encourage the little ones imagination.

My daughter likes to make her own stories, and for me to join in too. It's fun. Helps build upon her imagination and creativeness.

A great toy for imaginative play. May tip if a toddler tries to use it to pull themselves to a standing position.
