First and foremost, I did quite a lot of research in terms of price, delivery and also client assistance before I finally made the decision to work with Zen. They were the first company to reply to my request for samples, emailed to me by a "real" person, not a computer generated response which seems to be common place in today's market. I received the pens, called and spoke to Paul and with each and every email, I would get a response within the hour if not sooner. Every step of the way was directed by Paul to ensure that our order was delivered in a timely manner and in the exact colours, specs etc that we requested. This is the way Customer Service and delivery should be. I commend Paul and his team and will absolutely recommend them and use them again.
