Colo Majic is a brand of ostomy pouch liners designed to work with two piece ostomy bags. They are placed inside the ostomy pouch, which allows you to empty the contents without having to replace a whole new bag. This can be more cost effective and also makes it easier to change your bag in public restrooms. Colo Majic liners trap odors and are easy to dispose of. They are more compact than a normal ostomy bag, making it easier and more discreet to take on the go. Colo Majic liners are biodegradable and flushable.
