Pill Pendant

Like most people with a deadly allergy to nuts, I've always had to prepare for the event in which I accidentally consumed them. Some choose to carry EpiPens, but what I find works for me are antihistamines or Benadryl. This pendant prepares me for the worst-case scenario; it's a highly water-resistant capsule that holds two Benadryl pills.*
I designed it for easy opening. It's a two-part system, with a top and a bottom half. The top half attaches to a necklace, and the bottom half holds the pills. The top half has a grooved texture for a better grip, and the bottom half has an ergonomic design that fits nicely between your fingers.
I made this case to specifically hold two Benadryl pills, as well as a small cotton ball. If you're curious, the dimensions of the space within the pendant made to keep the pills is 4.61 mm x 6.60mm x 32mm exactly.

*You can submerge the capsule for two minutes, and shower with it without any problems. It's nearly waterproof, but I wouldn't go swimmin
