I have had contact with this company regarding a 3D pen. I was very well supported and received a lot of help. The employee Lin Da explained everything to me with patience. Great prices could be better but for the first order of 200 pieces and 1000 packages everything was perfect. I bought a test product and it went very quickly. The CE certificate was not up to date, so I contacted Wingh Zu and he promised me that I would get it in a week, so everything went very well and you get very good support from everything in this company. There are always answers day and night.

Wing is a trully great person to work with, excellent communication and products
