This pill box has 7 trays for each weekday and each tray has 4 compartments specially designed for 4 doses a day. It has been constructed to eliminate confusion that many seniors and elder persons often encounter while managing their medicines. In fact, it’s a great medication reminder for all ages.  Sleek-designed trays are discreet and easily fit in purses and pockets to take with you wherever you go.  When you pull the day’s tray out of the bottom of the  pill, the next tray slides down into place. Simply refill pill pro by removing the top.
