The Simplicity Hands Free Pumping Bra Kit is simple, effective and affordable! One size fits ALL (no hassle guessing at your size). Works with all breastpumps, all nursing bras or no nursing bra at all! Compact...fits in your purse, pocket or diaper bag. Easy...takes seconds to put on and off! The Simplicity is a fresh new concept in Hands Free Pumping and look very different than the corset types on the market. The Simplicity lets moms pump hands free but also enables hand massage/hands on pumping. When moms use the massage plus pumping technique surveys show they save approximately 5-6 minutes and extract 1.7 oz of breastmilk. This is huge for moms who work, have low milk supply, etc. Comes in multiple fun colors and has a 100% money back guarantee!
