Poppers

Now these are a really quick fix and the most economical of this type of fastening. Although economical, they are extremely good and just press together “pop” to fix semi-permanently. Available in black, white or clear, these are not only used for binding and swatches, they are frequently used as central pivots for games and spinning disks. 12mm head with a 5.5mm barrel these sit neatly using your standard 6mm/6.5mm hole punch. The capacity/size of the popper is measured by the distance in between the two heads when closed.
