Small compartments with lids (Rockville)

It's similar to a weekly pill taker box, but it only has 3 sections. It's about 5.5 inches by 1.5 inches. It seems like it might be useful for something, but I don't actually have a use for it. There are some walls inside each compartment which could be inconvenient if meds were stored in it. And there are small holes in each top and bottom -- not large enough for a pill to go through, but it means that it's neither air-tight nor water-tight.
