Skin Food's Seaweed Waterproof Eyeliner

Sounds malansa? LOL!  I know but this shade is really good on me.  It's my favorite so far (since this is my first ever eyeliner).

But I need HELP!

I don't know how to lengthen the tip.

It's not supposed to be sharpened.

Does anyone out there know what I should do?
They don't have it in Skin Food stores in Megamall.

They have another kind. :(((
