I see that as a nice little module. I think the glass vial is a bit overkill for the fishing kit. However, it is a nice perk....should I buy one I would likely dump the contents into the plastic bag and use the vial for something else.

Many times folks trying to make up a kit are faced with buying a box of 100 hooks in 2 or 3 sizes and then only using a few....this alone could make a module like this a useful purchase.

Adding a 2/0 or 3/0 gaff hook would really be nice.
