Review: Schmidt rocks! - Perfect. It fit my legacy Rotring 600 3in1 perfectly and I am very happy I can use again my favorite writing tool.
Review: PERFECT! - I purchased these 2 little pens 20 years ago and I love them. They are teeny and fit in my wallet perfectly. They FINALLY ran out of ink and I had no more cartridges. I attempted to purchase a couple others but they were wrong. Then I found this seller. They came fast and were packaged perfectly. I love how they write and YAAY!! THEY FIT!!! Now my cute little pink pens are back in my wallet where they belong and thanks to this seller, they will now live forever. haha :) Best part of the transaction was the lovely little note that the seller included in my package. He included several little inserts for his business and thanked me for ordering. That was really nice. They have super fun things in their store so I have some good ideas for Christmas gifts. I appreciate when sellers go that extra mile to let me know I'm appreciated. Good business, good products, good customer service!! HIGHLY RECOMMEND!!!
