Talking In Wechat About Paper Cutting Knife

Most people including me will choose to send email to learn some products that we are interested in.  But I think it's better to talk by whatapp or wechat. You can get the machine knife information in time and increase the trust between both parties. 

Now I am talking with a customer who is asking about Perfecta 115 paper cutting knife, he can get my fast response. Don't you want to cooperate in this way?
