I previously shopped at Pendamonium's store in Charles Street Plaza in Adelaide before they shut down the shop front side of the business and focused mainly on the website side of things.

I have not been disappointed at all through the website service. The service is quick, affordable (10% off most other retailers and even less through the internet).
I found when I was unsure about what I wanted to buy, the Owner was willing to meet me in the city with some pens to try out and best decide what I like.

I will continue to shop with them, as pens are a great gift and some of the items they stock are very nice.
