I bought the Sassy lively links for my first son and they were one of the first toys that he could play with. They fit perfect in his little hands and the are easy to put togther and pull apart. The links come in all colors and are very bright and there is also a black and white one. Also the sassy lively links will fit all the other brand of links, so they can be played with together. The lively links are one of the toys that I have decided to keep for my new baby. My son really liked these and they are small so they don't take up a lot of space.
