A holding case for the Powkiddy RGB30 Device that uses the foam protector as padding. The foam padding insert will securely sit in the base without any interference. The tab is not really needed, I added it for more security when in my backpack.
To slide in, I go shoulder side first. It can be popped out either by grabbing by the thumb indents, or by pressing through the hex pattern on the face.
