The influencer Stationery Bee played the game of comparison. She tested the black grid METIS from the YOOKERS Premium range and the YOOTH 549 Blue Ocean model.

Two ranges – one luxury, one more economical – but, if the bodies differ (some are in steel, others in resin), all the models are equipped with the system which makes all the originality of the YOOKERS brand: you can change the diameter of the felt tip without changing the body of the pen and all are refilled with universal standard ink cartridges or with a converter* and an ink bottle. * except for model YOOTH 751 that is too thin to fit the converter.
