We've taken into consideration the customers who take only a small dose of daily meds and/or are in the need for a compact pill organizer that they only need to fill once a month. Introducing the "MedCenter Mini". Each of the included eight Pill Boxes contains four, numerically marked, compartments for each day of the month. This gives you a total of thirty-one daily compartments in the most compact monthly organizer we have available. Our new larger XL Pill Boxes (used in all products denoting the "XL" size pill boxes, also available as an accessory to the exisitng MedCenter System) have an individual dose compartment which measures roughly 1 3/8" wide x 1" long x 3/4" deep on the inside. Each of the new XL Pill Boxes contain four of these dose compartments.
