Molotow DRIPSTICK Empty Squeeze Bottle Marker, Reusable and Refillable with Any Paint Ink Color, 25mm Nib, Holds 100ml (830.204), Black

I saw this advice on an Ozark Leather Company video. Someone in the comments mentioned using a refillable bingo marker and said their mix is roughly 2 parts tokonole to 1 part water. Searching for bingo markers turned up nothing but cheap generic stuff that did not look that great, but I imagine something like this would work nicely https://a.co/d/0416k0TU
