  • This mass set is great for children of all ages. The different colors make it easy to calculate the mass. My children have had a great time measuring all sorts of objects.

  • I purchased this set for use in after school class for K-5 kids. The set is ideal for their use: the pieces are solid, easy to handle, and easily stackable. Great product!
    Great set of weights

  • This is a great set of weights. My four and three year old have no problem using them, the color coding makes it easy, and there are enough weights to weigh small items around the house. I received the items in a very timely manner, and am very happy with my purchase.
