The Boob Boss Nipple Ruler (Visual Tutorial Included)

Take the guesswork out of your flange sizing The Boob Boss Nipple Ruler. I designed this ruler with you in mind - creating a measuring device that is both inclusive (covering the widest range of sizes), and ergonomically designed to ensure comfort without compromising accuracy. Made out of 100% food-grade silicone, the ruler is not only buttery soft but also has antimicrobial properties that will help protect your nipples. A visual tutorial is included with your purchase.
