The popular Gelion 39 refill has now been rebranded as the Gelion+.
The "new" version uses the same ink and point size to give a 0.4mm nominal line width, giving the same performance.
Schneider now specify these refills as 0.7mm; this refers to the diameter of the ball used - not the line drawn.
Please note, during the transition from old to new style packaging, you may receive a mix of Gelion 39 and Gelion+ branded refills.
