For all these years now, I'd been tossing these in the trash after snipping them out. Seems tired/expired caps are all the rage, nowadays, maybe someone on AK can explain the allure of leaky caps to me. If I were to have ten dollars (yes, $39.99 for four, look at this listing) for every 50-plus-year-old bumblebee or black beauty turned flyback-killer I tossed, I'd be quite wealthy.
