OnFireGuyAir-Tite Black Wafer Capsule Holders for 1Oz Or Smaller Gold Bars, 3 Pack

How to open the case once fit?

The bars have to be loose tho yes? Is there a case that can hold bar incased in coa?

If putting 1g or 2g in these, is there a way to keep them from moving around? Just wondering how they fit and if mult fractional bars can be stored.
