I am quite disappointed with the product I got. I thought Eduspark is an Indian company and would be sourcing/manufacturing its products in India, but what we got was a Chinese product. Even the instruction booklet in the product was in Chinese. Also the shipping document said that the product is a sample and not for resale- you must be saving customs duty on it.
The chalk we got with the product was extremely dusty, which is hazardous for the kids. You should at least ensure that the products you are selling are non toxic and non hazardous for the kids.
