Place the washable sizing card flat against your skin, directly over your stoma. The card features a range of openings from 2mm to 62mm. Find the opening that fits snugly around your stoma without being too tight. A proper measurement is the most important step for a comfortable, leak free fit. We recommend measuring regularly as stoma size can change over time, particularly in the months following surgery.

Place your ostomy skin barrier face down into the CleanCut™ device, centered over the cutting mechanism. The device is designed to hold the barrier securely in place while you cut, so no additional grip or pressure is needed.

Once you have identified your size on the sizing card, turn the dial on the CleanCut™ device to match that measurement. The dial rotates smoothly and locks into each size increment with a clear, satisfying click. Make sure the indicator on the dial lines up precisely with your chosen size before moving to the next step.

Push down firmly on the dial to lock in your selected size and engage the cutting blade. Using the outer knob, rotate the device in a full 360 degree circle. You will feel and hear the blade moving cleanly through the barrier material. One smooth rotation is all it takes.

Open the device and remove your barrier. You will find a perfectly circular cut opening that matches your stoma size exactly. No jagged edges, no guesswork, no wasted supplies. Your barrier is ready to apply.
