I bought these as a cheaper alternative for my pilot v5 fusion 0.5mm pens that I use at my job. My job we write in very small fields and I was hoping these would be a great replacement. Unfortunately, they are not what I expected. The are good pens if you are looking for an low cost alternative for the pilot g2 pens. However these are not lefthand friendly. They smear just as much as any other gel ink pen. Also they are definitely not 0.5mm. These are more likely a 0.7mm pen. To those who don't care about point size these are great pens. But I bought these for the purpose of the point size. I have included a few photos of a side by side comparison of this pen vs the pilot 0.5mm. Clearly the pilot needle appears thinner and it writes thinner as well. Both are not smear proof. I will still be using these pens around my home but unfortunately for the intended purpose I can not use them. Also these pens have a red peel off thing on the end on the pen. It's there to prevent it from drying out. This is great However it was difficult to remove without getting ink all over my fingers. I do think they are great price for the amount of pens you get but again not for what I needed. If you are going to advertise something make sure it does what it says and is the size you claim it to be.Pens were just as described, the packaging honestly shocked me and I thought I’d been delivered the wrong item, but sure enough the pens were inside and I was reminded that “the world is so wonderful it deservers us to struggle”was spotty ink writing on first useDe Gran interés y utilidadThe packaging has a misspelled word in the odd quote...."The world is so wonderful that it deservers us to struggle"I love pens. I even collect them. I am constantly frustrated by cheap pens or accidentally borrowed bank pens. Some of the nicer pens I own are not refillable or get borrowed or lost. These pens came recommended by a friend and the price was great for 30 pens! From the first moment I wrote with them I was in love! It glided across my page smoothly and elegantly with narry a blob to stain my paper. It driend instantly and didn't smear. Now I am hoarding 10 for myself and gifting a pack of 10 to my dad and to my collegiate nephew as stocking stuffers. Seriously. To find such elegant pens at such an affordable price, you cannot beat this. Best of all, they have no issues with glossy paper such as receipts either.They feel like cheap G2 pens, we’ll see how long they lastPens are nice but it is hard to get the plastic of the ends in order to start using them
