My dad has to take a pill every day to cure his condition. Often, for short trips, we forget to take the blister pack of tablets.

I thought that a pill container keychain could be the perfect solution for these rare oversights.

As a closure I thought of a screw, it is quite difficult to screw and unscrew, it was made on purpose so that the medicine could not be lost by mistake.

There are some variations of the same:
- A longer one with a diameter of 1.2cm that holds 2 pills;
- A shorter one with a diameter of 1.2cm that holds 1 pill;
- One with a diameter of 1.6 and a height of 2cm;
- One with a diameter of 1.6cm which can be extended as, in addition to the cap, the bottom also screws on.
