The one and only corrugated plastic tubes that make an amazing, addicting sound when pulled open and pushed together. 7 inch long, vibrantly colored pipes expand to 28" when fully expanded. Pipes can be linked together and bent to form twisted designs and marble mazes (sorry-no marble included). Great for developing hand, finger and arm strength, hand stability, bilateral coordination, motor planning and visual and auditory attending. 12 pipes to a set.
love these!09/11/2018 ByMarie My kids love these. They use them everywhere. home, bath tub, beach, even take them to grandma's house. My kids are 8, 6 & 4 1/2 and they will play together with these. I have bought a few of the big packs over the years, so they have enough to share. They will break if left in the car, or stepped on- but overall seem to last awhile.
