Ik store the gelatine capsules in a small plastic zip bag and that works well do far.

Hello John,

Many years ago I tried this, however in the part of Europe I live the
temperature and humidity in summer is such that gradually the capsules
deteriorate (they become yellow and brittle) even when put in a glass
vial (I was able to recover the shells by just dissolving the capsules
in warm water). I therefore stopped using this method. There are many
sites on the Internet which offer small vials/boxes for laboratories.
That's the system I'm using currently and until now with no problems.

Erick
