Zerodh brokerage on penny stocks

Hi All
could you please confirm what is the zerodha brokerage charges On penny stocks , like Kss Ltd.
my colleauge has

I’m assuming you are buying these shares on delivery, if yes the brokerage is a nil - you pay 0 brokerage. I’d suggest you read through our brokerage calculator for brokerage applicable for other kinds of trade - https://zerodha.com/brokerage-calculator

Just 1-2 months back people were assuming that KSS is going to isolate , they are going to and now they many are investing in it for long term . Hardly there’s any intraday I think !! Is it safe for holding for like 1-2 years ?
