Nothing much to add: if you have a Orenz Metal Grip v2, these are no different. Just wanted to share some real world colors of these 4 that just came out in late January.
Of note: Pentel chose to do only 0.5mm, compared to the usual assortment of lead sizes for a limited run. This feels a bit ominous given the fact that the Orenz line was built around the revival of usable 0.2mm.
