I bought and applied some Jockomo inlays a couple of years ago and, man, was it nerve shattering to get centered and try to not ruin the glue by holding them too much, I actually messed up the corner of one a bit.
Bought some more to do the first fret on same bass cuz, yeah, I didn't know that inlays went on the first fret space since my only experience was with fret dots which don't normally go there. This time was easy because there is now an oversized clear strip of film over the inlay so you can hold easily without touching the inlay/glue itself and precisely center since your fingers aren't in your eyes' way. Can't go wrong with these inlays now.
