I bought these Link-A-Doos originally to go with my Floppy Seat (which I also wrote a review on lol) so I could clip my daughter's toys to the loops. They were such a good investment! I keep some of them with the Floppy Seat for toys, some in her stroller to attach toys to that, and some in the house just for her to play with!
The set of twenty plastic, interlocking rings comes in many bright colors. Ten are just plain rings, ten are in the shapes of animals, which are really cute! These ones are the ones my daughter likes to play with and chew on, so they double as a teething toy.
My daughter recently discovered her inner pitcher (we're going to audition her for hte Red Sox pretty soon), so these rings are fantastic at keeping her from pitching her toys out of the cart/stroller/whatever, thereby saving the toys from getting dirty, and our backs from pain from continually bending to retrieve said thrown toy.
You can also buy other Link-A-Doo toys that are specifically designed for linking with these rings, and I fully intend on getting some.
Make your life easier- get these Link-A-Doos and stop playing pick-up everywhere you go!
