Customer Reviews

Koloro Demonstrator
I really am enjoying this pen. Shows the ink very well which is the wonderful thing about demonstrators. And the ink capacity is tremendous! The nib writes very well - thank you for checking it out before sending it. All in all, a very satisfying pen purchase.

Love this pen. The stub nib is juicy and writes smoothly. The lock down option makes is a great traveler. Also pluses are the clean, classic look and ink capacity. Not postable, if that’s a consideration.

Pretty nice fountain pen with good, wet writing nib. Please note that this is big pen, so the functionality of it depends of how big hand you have. Grip could be just a little bit more thin to make it perfect.

Koloro Demonstrator
A truly great pen. Ink capacity is amazing. A true demonstrator that features your style of ink choice. I am a left handed overwriter so the EF nib works great for me. Love fine lines, less chance of smearing. Pilot Iroshizuku ink is what I use and for any lefties thinking of moving into the fountain pen world, this is your ink. Ordered on a Monday evening and pen arrived Thursday afternoon...very happy with that. Will be buying more from Opus 88.

The pen writes wonderfully, its larger than normal size feels fulfilling and has more space on the grip than its cousins to hold the pen properly. I am very happy with my purchase.

Nice big pen. Typically flawless Opus 88 finish, Broad was a little wide for me so I ordered M and F nibs. Have two more Omar’s - great pens!

Koloro
I have really enjoyed this pen. It is very lightweight, but is a good size and has a nice feel. Impressed by how smooth the medium nib I ordered is, and how the line is just right — not too wide, not too narrow. It is among the 1-2 best steel nib pens I own. Surprised Opus isn't talked about more. I got it on sale, and it was well worth. Also, holds a ton of ink.

I do like the dedicated eyedropper concept with the release valve. It works rather better than my attempts at "eyedroppering" cartridge pens. This is a good pen, if a bit on the large size for my personal taste. Unfortunately, I think the fine nib on this was a poor choice for me. It seems more like an extra fine, and is a bit of a dry writer. I later got the Opus 88 Picnic model with a medium nib, which is more like what I would consider an actual fine, and suits me much better.

A good functional eyedropper pen. A bit fatter than I find ideal for my personal taste, but still comfortable enough to hold. I like the medium nib, which writes quite smoothly and is on the finer side of medium, good from my point of view. I find this easier to fill with a syringe and a long blunt needle than with the included eyedropper. Every now and then, when writing at greater length, it's useful to crack the vent on this to give the flow a boost. Attractive enough without being in any way fancy; I got it in the brown. Holds a lot of ink, although I neglected to measure how much I put in on the first fill. This makes a good pen for work, where I want good performance and high ink capacity, but may not want to risk one of my nicer vintage pens.

Omar
The Omar Amber is my third Opus 88 pen, following the first and second editions of the Koloro. This pen is BIG. I like the filling mechanism and ability to close off the feed (great for flying). The nib is delightful to write with. I have Fine, Medium, and Stub (which is my favorite in this pen). The drawbacks are few, one of which is that the cap does not post. This may be an issue or not, as the pen is big enough for my large hands to use unposted, but my preference is for pens that post. The second is that the resin cap is deep, colorful, and a delight to look at. Unfortunately the pen does not have any of the cap’s treatment and is monotone brown with white end cap accents. I really wish the marbling of the cap was carried over to the pen in some fashion. Overall the pen is reliable, comfortable, attractive, and travels well. It’s a keeper.

Koloro Demonstrator
I think Opus 88 makes some amazing pens. I have the Kolor Demonstrator in all the colors and 3 Clear Omars. Fantastic size to encourage a relaxed handgrip and a wonderfully tuned nib out of the box to boot. I have broad, medium, and fine nibs. I'm awaiting a stub.

Omar Demonstrator
Opus88 makes wonderful pens, the Omar Demonstartor
is no different. The sleek construction of the pen feels great in the hand. The eye dropper filler holds a generous amount of ink that doesn't run out quickly. And it writes like butter. What more can you ask for in a pen?

Koloro Demonstrator
I purchased this pen with a stub nib. The first one just didn't have great ink flow. It railroaded easily and had many hard starts. The replacement pen that Pen Chalet sent (super fast by the way) worked flawlessly out of the box. It is nice and wet and a very smooth writer once you become accustomed to a stub nib. I own many pens that are significantly more expensive, but this is one of my favorites to write with. The size is perfect for my hand. The nib makes my handwriting look better than it really is. One thing I learned is that you really do need some silicone grease where the feed screws into the section. There is a little o-ring in there, but it is not sufficient to prevent ink from flowing through the section around the outside of the feed and nib.

Medium nib is not too broad for my taste, and I'm usually a fine nib guy. Works great! Smooth writer. Nice ink capacity. Love the look too.

I absolutely LOVE this pen. It's girthy around the section, which I like, and the medium nib writes wonderfully.

I'm simply returning for a direct exchange due to a minor defect, but the customer service is second to none to get it sorted. I do all my shopping here.

I am very happy with this pen. Bought it mostly for the appearance, but I love the filling system as well. The nib wrote well right out of the box. When I filled it for the first time the ink wouldn't flow to the nib, even after sitting for a good long time. After removing and rinsing with water, it flowed. Fairly wet but not a gusher.
