ProCase Watch Case for Men, 14 Slot Mens Watch Box Holder Organizer with Glass Lid, Watch Display Case, Fathers Day Gift for Dad Husband, Birthday Valentine Gifts for Men Women -14 Slot, Black

I count 45 on that list. Get yourself two of these: https://www.amazon.com/ProCase-Display-Removable-Organizer-Collectors/dp/B0FK4L5V22 Then the deal is that once they are both full you have to sell or give away a set before you can purchase any more. 48 IEM's will allow you to use a different set every week, and your favorite four you can use for a second week each. Alternatively, get three of the cases linked below (14 slots each) and have exactly 52 slots, one per week. https://www.amazon.com/ProCase-Organizer-Watches-Birthday-Christmas/dp/B0FH9L6T3R For extra fun, order them ahead of time to match the week of the year they will be used, ensuring, for instance, that you have fun light non-weighty ones for Holiday music, and heavier ones for the weeks around Halloween, your favorite of all of them for the week of your birthday, etc.
