Dunno when can I find a new nib replacement...

Yup.. finally the pen nib has worn down.. to less than 1-2mm... That's why these day I didn't draw or paint much.. I have to find new pen nib... in the meantime... I am try out other method...

yup.. using toothpick..(info from Internet...)

as a current replacement.. (I must be mad... lol..) the sensitivity is horrible.. of course, I have to use plastic or anything I can get my hands on to cover the tablet.. Otherwise.. can't imagine...
