I use a MAC pump with a Nars foundation (Pictures)

the too faced born this way pump works perfect for the threads. just had to trim down the stem as its a taller bottle.

I needed a pump for my Nars Sheer Glow. As Nars pump is impossible to find I thought I could use the MAC one with plumber tape (veda rosca em Brazil). This pump is available everywhere either original either similar ones.

It worked like a charm. Pass some (many😂) strips of tape around the bottle mouth to enlarge it and voilá. The pump will fit perfectly.
