Patch Poppers are indeed a great tool to have on the line
for dispensing patches as we wipe with or dry behind bore pigs.
I have been using an alternative for some years for convenient
and fast organized dispensing of patches on the line.
See attached PIC of small square Rubbermaid or similar tubs
with "spiral layered "patches that are easy to pick up. Just need
to pre-stack the patches thusly in advance.
