Have been using them for years. Brilliant company. Really know their stuff. Started with mostly ink cartridges and photo paper. But now filliment for 3d printing. Their own brand ink, photopaper and filliment is superb. It has never failed and the ink carts are as good as the branded ones. A fine irish company who really know their business. They are better than Amazon all day long. I always look for an irish company first before resorting to Amazon. A lot of irish companies fall short of the mark for value,service,available products and service. 123INK AND 123INK-3d are 5 stars in all categories so I am Proud to support them.
