Everything in this box is necessary and a great tool to have for first-time mothers who aren’t sure and do a lor of research on their own. I love the various sizes and the measurement tool. Thr instructions are simple and I feel more comfortable and confident now.

The sizing chart is super helpful and the flanges fit great. I just wish there was a way to order the size I need and not the entire sizing kit.

Easy to use- love that you get to try all of the sizes
