New bottle of soy sauce has a pull-to-open seal with a ring attached for pulling. The ring detached when I pulled it.

Hypothesis 1): I am bad at pulling these sort of rings in the intended direction.

Hypothesis 2): These ring-things are flawed in design.

(Eventually the bottle was opened by abusing a small-medium-ish screw driver by inserting the flat tip against the raised area of the seal and exerting force down then up. Couldn't help but feel opening a bottle should require less effort than this.)
