GMS 7 Day Small Stack-able Pill Organizer has been significantly upgraded, including the thickness of the plastic and the threading around each individual compartment. The new design is very sturdy and the compartments twist onto one another smoothly and more securely than ever. This product also includes pre-printed adhesive labels for each day of the week for easier organization. The seven lids included allow you to take individual compartments with you, making travel a breeze. All seven compartments are completely clear for easy identification.
