The trouble with purchasing pill boxes on line is that the size of each compartment is not clearly specified.
The inside dimensions of each compartment are:
7/8" long x 15/16" wide x 3/4" depth
The outside dimensions of the entire pill box in its leatherette case (28 compartments):
7.5" long x 4.5" wide x 1" height
I take two 600 mg Calcium pills, two Omega 3 capsules and vitamin D on daily basis. I was able to fit these five pills into one compartment. It was very tight but I was able to close it.
The compartments close well and does not open I shake the box. Each box is well marked. Each day is a separate box, which works pretty well especially when I travel.
Bottom line: Good construction, closes well, labeled well. Leatherette case keeps the box from opening while traveling even if the luggage it treated roughly by the handlers.
The package also includes a pill cutter. It works quite well, in attached video you can see me cutting Calcium pills. Even those large pills were easy to cut and the cut is very clean.
You can find it on Amazon by following this link.
