Every body is different. One person may need the straight edge at the top, while someone at the bottom. Someone else may need the straight edge to the right or the left. We get it. For this reason, our pouches come in all directions. You place the straight edge however you need that, and don’t worry if it turns our D into a U, or some other shape. Our drainable and closed pouches each come in four different directions so that we have whatever you and your patient need.
