i currently am painting in Argentina, and i have confirmed that the yellow and ONLY yellow sekt adapters work on the male stem domestic argentine brands that u can find in most hardware stores down here.
there is a brand called KUWAIT down here that does have a graff line that does include a female valve. therefore most of the male caps that are on the AP site will work on the KUWAIT graff line.
i definitely recommend trying the KUWAIT graff if you come down to ARG. you can find it in most graff shops and in some paint/hardware stores, but your best bet is a graffiti shop for sure if you want cop some.
i would put it on the same level as flame blue.
aight look, this pilot silver is blingin! cop this! the silver ink/paint is da shizzle, so clean and buttery, run it on smooth surfaces, and flare the nib out for dope writes. if you cop it, buy two or three, then empty one into the other then u have a full marker and a extra nib. i found mine at office deals, but AP is the sh*t so give em some love and cop this!
