The pen looks really cool from a distance, but when you touch it, it feels much cheaper. It is definitely not golden, I don't know if it's gold electroplated or not, but looks like such. The nib size is fine, finer than my Waterman Phileas F. The pen takes international standard (small) cartridges and the nib has a beautiful engraving on it. I haven't tried a converter yet. It is a very smooth writer, starts well and does never skip. It spent several years unused in my drawer and the all the ink had evaporated from the cartridge. The pen was so dirty that I thought it must be wrecked but then I cleaned it, changed a new cartridge and it started writing just fine.
Here are some photos of the peb and a sample of my terrible-looking handwriting. Please don't blame the pen, it's all my fault!
