Beautiful vivid colors! But tends to bleed through.

·Stiffer and stronger tip than most other calligraphy markers I've tried.
·The small side is roughly the same width as the small side of the Metallic Zig, but the large side is noticeably wider.
·One was initially dry (if you look next to the green "calligraphy" I've pictured, you'll see on the left how I had to work it a bit to get the ink flowing again).
·Pigment is good. Shows through on the back side of medium weight paper, but no excessive bleeding.

I have been writing in calligraphy for over 25 years and have used a variety of calligraphy pens and markers. I really like these calligraphy markers compared to other brands of calligraphy markers. Each marker is double-sided with one 2mm and one 5mm felt tip. This is a nice and practical feature. I prefer to use the small tip most of the time. This set includes pure red, pure green, pure blue and pure black markers. The colors are very bright and vivid. I use these markers for scrapbooking and for writing names on the envelopes of greeting cards and invitations. The ink is acid free, photo safe and archival quality which makes the markers perfect for scrapbooking. Calligraphy on envelopes always looks elegant and sophisticated. I always get compliments on my writings. Many recipients of my cards and invitations say they save the envelopes.

I would like to note that I used fountain calligraphy pens for many years. The ink flows smoothly and the writing looks sharp. However, there are disadvantages to using fountain pens. First, the ink in fountain pens is not colorfast and fades with time. Second, the ink I used was not labeled as acid free, photo safe or archival quality. Third, the ink in the nib will dry and clog the nib if not used for a while. This was actually my biggest pet peeve. As I was not using the pens regularly, I would often encounter this problem. Lastly, fountain pens can sometimes be messy. They can leak for a variety of reasons.

I highly recommend the Zig Memory System Calligraphy Markers. I also bought a six pack of black Zig Memory System Calligraphy Markers. I plan to buy a larger set with more colors in the future.

As a marker set this is great. The only problem is I am no pro and when I pause in writing I cannot get the flow going, the result looks like chicken scratches untill I get the ink moving again. These are easy to use, have GREAT color saturation, and are not messy at all like some pen sets. The only reason I gave it four stars instead of five is because I have used other marker sets that work much nicer for me. A really good buy at the right price.

The colors are intense and the ink flows great with the tips giving sharp lines. The 5mm large tip is too big for medium work. A 3.5 mm to 4mm tip would be more versatile.
