## Questions & Answers

**Q: Do they come in a case?**
A: They come in a plastic package! You can call it a case.

**Q: Do these pens say "DX" on the cap?**
A: Yes, DX is shown on the clip-on part of the cap.

**Q: Do the pens write on black or dark paper?**
A: No, it's not opaque. I LOVE the Signo gel pens and have tried almost all the models. The Uni-Ball Signo UM-151 does come in 8 opaque pastel colors and 8 metallics, but they are not as fine (0.7mm instead of 0.38) and are not included in this set. You might also look at the Uni-ball Signo Angelic UM-120AC (0.7mm, 8 pastels), Uni-ball Signo Noble Metal Metallic UM-120NM (0.8mm, 8 metallic colors), and Uni-ball Signo Sparkling Glitter UM-120SP (1.0mm, 8 sparkling colors). Finally, if you're okay with a broad tip, the Uni-Ball Signo UM-153 Broad Point pens are smooth as silk (1.0mm, white, gold, silver).

**Q: Do they make Uniballs signo in broad tips with this color selection? Uniball you have millions of colorists that would use asst. colors in broad tips**
A: This UM-151 0.38mm comes in 32 colors. The UM-151 also comes with 0.28mm and 0.5mm tips that are each available in 17 colors. The 0.7mm tip is available in 8 metallic or 8 opaque pastel colors. The broad tip UM-153 (1.0mm) has only 8 colors, 3 of which are opaque (white, gold, silver).

## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    The best brand of pen
  

*by A***R on Reviewed in the United Arab Emirates on 27 April 2021*

This is waterproof and fade proof, for writing I prefer this 0.38mm hence I am giving it a perfect score. However for artists you might want to try the 0.28mm

### ⭐⭐⭐⭐⭐ 







  
  
    Excellent quality gel pens
  

*by M***L on Reviewed in Canada on 31 August 2016*

Excellent gel pens. Top notch quality ink. And they glide smoothly on the paper for such an extra fine tip size. Some are more scratchy then others, but it's not really noticeable.Overall I am VERY HAPPY with these pens and would recommend them for those who want a fine line pen with a burst of colour.Wouldn't expect anything less from the Uni-Ball Signo series. :)

### ⭐⭐⭐⭐ 







  
  
    Smooth and Colorful assortment
  

*by O***U on Reviewed in Canada on 20 August 2019*

These pens are very colorful, quite an assortment, and they write VERY smoothly, but the tips are smaller than I expected.  I highly recommend them for writing, but definitely don't recommend them for artwork/coloring unless you just use them for detailed work, such as outlining because they're so small.  It would take too long to fill in even part of a page.  I recommend them.
