Does the job!
Much higher quality than I expected!  It is a wee bit large and heavy for a key chain, but not too. If it were smaller, it would not have capacity and if it were lighter, it would not secure your meds so well.  The shape of your meds will determine capacity.  With &#34;aspirin&#34; shape I get 15 in the top chamber and four of the &#34;capsule&#34; shape in the bottom.  The pictured capsules are just a tad too tall to sit vertically in the chamber.  You cannot fill to the rim because of the highly functional deep threads.  This holder will protect meds perfectly.  It already saved the day for me on an extended absence from home.
