These are simple to connect and take apart for my 3/4 year olds. They loved to build with them and show off their creations!

Love it

The kids love building with these pipes and seeing what they can make with them.

These are perfect for arrival activities!

Got this for my son as an older toddler (age 4 or so) after playing with a set at our library. He played with them often, and once little brother was old enough they were able to play together. Easily enough in this set for two children to share. They are now nearly 8 and 3, and they still play with these together. Some have cracked (when they sword fight with their creations), so we've had to toss a couple here and there, but they're pretty durable and we still have plenty.

My preschoolers love it when I pull these out!

My students love building with theses. They are high quality and easy to clean.
