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.
Great at first and the pens work well. Mild odour so not an issue. After two weeks of very mild use...I write my workout routines down...the green and black pen completely dried out. Quite disappointed since this product had so many good reviews.
Wouldn't buy again. Two of the markers were almost completely dried out. The other ones are okay but they generally don't erase well without using the solution. Waste of money to get this kit if you ask me.
