Ohuhu 320-Count Alcohol-Based Marker Set Review: Massive Color Range, Clear Trade-Offs

Introduction

Ohuhu made its name back in 2018 when it launched a 40-count alcohol-based marker set that blended well, performed at an artist-quality level, and came at a price far below the established competition. This set is the logical extreme of that formula: the entire Ohuhu alcohol marker collection combined into a single 320-count box, which the company describes as its largest alcohol-based marker set ever released.

First Impressions and What’s in the Box

The first thing you notice is the sheer size. This is a genuinely heavy kit, weighing 14 pounds, and it dwarfs a standard 60-pack many times over. Alongside the markers themselves, the box includes a few thoughtful extras: a thin plastic sheet to place under your paper so ink does not bleed through, a color booklet covering every color in the set, and a pre-printed swatch board you can fill in yourself. The swatch board is split across four sheets because there are simply too many colors for one.

One small editorial wish: with this many colors, the case itself is not color coded, so hunting for a specific shade can feel like a search puzzle. Arranging the markers by color family after unboxing helps enormously.

Barrel Design and Color Naming

The marker barrels carry a few refinements compared with earlier Ohuhu releases. Small indent grooves have been added inside the caps, which appear to make the markers easier to pop open. More importantly, every marker now has an actual printed color name.

That may sound trivial, but older Ohuhu sets used only numeric codes, and remembering which marker was “E475” is far harder than remembering a fun, descriptive name. For anyone who mixes colors regularly, the named barrels are a genuine quality-of-life improvement.

Swatching 320 Colors

Filling in the swatch board is a serious commitment; the full process takes around three hours, most of it spent locating the right slot for each marker. Once done, though, you have a complete visual index of the entire set. Standout colors include a strong range of fluorescent shades, which make artwork pop like almost nothing else.

There are also some oddities. A shade named “further color of skin” is hard to parse, and “black brown” turns out to be a vibrant pastel pink rather than anything brown or black. With 320 colors, a few confusing names are almost inevitable.

Things to Consider Before Buying

Two colors deserve special attention: there is only a single colorless blender in the entire 320-marker set, and only one pure black. Both are the markers most artists reach for constantly, so they are likely to run dry long before the rest of the set. Ohuhu does not sell refills, and unlike some competitors there is no refill option here, so once a marker dries out it is done for. Ideally the set would include several blenders and blacks, or offer them individually.

On paper behavior, bleeding is very standard for this marker type: moderate bleed-through to the page beneath, and minimal transfer past that, even with heavy pressure. The ink formula itself appears unchanged from the earlier Ohuhu markers, which is good news since that formula was well received for blending.

Who This Set Actually Makes Sense For

This is where an honest assessment matters. The color range is mind-boggling, and having every color you could need in one box is genuinely reassuring. A version of this set with a brush nib instead of a bullet nib would be nearly perfect for many artists.

But for most people, 320 markers is more than necessary. Unless you are producing artwork constantly, some of these markers will likely dry out within a year or two before being fully used. For many buyers, starting with a smaller pack, such as the 40-count for around $20 or a 60 or 90-count set, is the more practical route. This large set makes the most sense for artists who genuinely want maximum variety in one purchase and understand the no-refill limitation.

Buying Advice

If you regularly work in alcohol markers and value having an enormous, immediately available color palette, this set delivers on that promise at a competitive price point. If you are a beginner or a casual artist, start smaller and expand later. Keep in mind that the single blender and single black will see the heaviest use, and plan accordingly.

Conclusion

The Ohuhu 320-count set is an impressive, well-built collection with beautiful color output, helpful named barrels, and useful swatching accessories. Its limitations, the lack of refills, the lone blender and black, and a size most artists do not truly need, mean it is best treated as a specialist purchase rather than a default one.
