I got these and the size larger. I prefer these personally. Both are good, but I work small and so these are best for me. as always, order came fast. I am happy with use and use them with the 33-114 backings. I have glued my fused glass works on them. I filed both the glass & the posts first & then clean with alcohol 1st. SO far none have come undone. Good to find an affordable surgical steel option. thanks!
