So, far as I can tell these are pretty nice white gel pens. I got them specifically for highlights on ink drawings and I think they'll do the job just fine. The only slight issue I noticed is that when I draw directly on the ink is that it initially goes down quite opaque, but dries significantly lighter, so you might have to put down a couple layers. Additionally as far as gel pens go the line it puts down is quite fine, which is what I personally was looking for.One other thing to note, these gel pens took a while to get here. But that's to be expected since they shipped directly from the seller overseas instead of from Amazon. I actually contacted the seller when the item was a week overdue and they were very nice about it. They said my package may have been lost due to everything going on so they promised to send a new one just in case. I have no idea if this is the new or original package, but either way I got my item, so thanks MISTERPEN!
