I believe Flex Coat Head Cement comes in a wide mouth bottle that has a lid for it that has a built-in bodkin for applying the head cement. BTW, the lid from the wide mouth bottle that ketchup comes in, you know the one that has the lid that is plastic and you just flip the top open and squeeze the bottle and when finished flip the top closed, will fit the Flex Coat head cement bottle and this will give you a small hole to insert the bodkin through to use the cement and then just flip the top closed. I use Sally Hanson mostly, but, will pour it into the Flex Coat bottle and use the flip-top lid on it. That sure beats unscrewing the lid on SH and then putting it back on. The flip-top can be opened and closed with one hand. The mouth on Flex Coat Head Cement is large enough to insert marbles, ball bearings, etc., if that is what you want to do. The bottle can be purchased full of head cement and a metal lid or a plastic lid with a built-in bodkin for applying the head cement. It can also be purchased as an empty bottle with either lid to put the head cement you prefer in it.
Just reporting my findings and not making any recommendations.

Fly fishing and fly tying are two things that I do, and when I am doing them, they are the only 2 things I think about. They clear my mind.
