To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Product is exactly what I wanted, it has several size pen nibs, lots of ink cartridges and also an instruction guide. I am looking forward to doing lots of practice with the set. The prompt delivery was very good also, received in a couple of days.
