This listing is for a 3-pack of medical sharps containers by one of the oldest brands in Sharps. You will get three one quart sharps containers with flip lids. These are the type of lids that pop open for safe placement of needles and other biohazard sharps. These sharps container lids do not come attached. They are sold to you detached. Because some people don't want to put the lids on right away. Once you put the lid on, it is locked for good and you must dispose of them
