Holds a split toradol SL 30mg and a single SL Zofran. Its pretty cool little piece. I'm not sure if you can tell from the picture, but there is a small gasket that seals the two halves pretty solidly (not sure if it's technically waterproof, but mine has survived immersion and showering) once they're screwed together. The cavity for pill storage is small, though, as others have said, so larger pills (eg. Advil or naproxen) are a no-go. Glad I have it, and I recommend it if your med of choice can fit.
