Canon Toner Cartridge 416Y

The packing of the product did not seem original and the sticker with price and Mfg. Date has been overwritten with a new one camouflaging the actual mfg.date and price. The quality of the print is bad

I found the best price after comparing with other sites and shops. I was wondering if this toner cartridge is fake as it was selling for so less than other places.
But now I am using this toner for last 2 months and satisfied with its performance.
