 Let's take a look at the Opus 88 Calorro fountain pens, two new colors in today's fountain pen unboxing. The Opus 88 boxes are really clean and simple with the Opus 88 logo inside. You have a little pamphlet full of really simple and clear again instructions on how to use your fountain pen. It comes with an eyedropper to use when filling your pen. And this is your Opus 88 Calorro, and the first one we'll look at is the amber and white version. The Opus 88 Calorro is a very popular eyedropper fountain pen, and we're really excited to see these two new colors amber and white and pink and white both have the colored portions that are like sparkly and it still gives you the demonstrator look without being completely clear. They are fitted with a stainless steel nib, and it's a Jovo nib, so if you've used those before you'll know you can look forward to this one. The Opus 88 Calorro pen design is postable with a friction post, and it has a threaded cap and a spring metal clip. The Calorro is designed specifically as an eyedropper with a control knob and a center bar inside the barrel to help control ink flow, and it's the type of eyedropper system that you typically find among higher-end pens, but the Opus 88 pens are much more affordable than you may expect. And here's the amber and white and pink and white side-by-side. Subscribe to Pinchelay for more new pens and inks.
