Fly tiers who need a wide color range in one thread purchase, since 16 colors of 3/0 nylon thread across a 90-yard spool covers most standard tying jobs without buying single-color spools separately.

The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less.

Context, not marks against it, and our read of the data, not a lab test.
Overview
Switching thread colors mid-pattern usually means digging through a drawer of single spools, and this 16-color, 3/0 nylon fly tying thread set is built to avoid that. At 0.22 pounds and 90 yards per spool, rated for a 33 line weight, it is sized for standard fly-tying technique rather than heavy saltwater rigging, and the 90-yard figure is enough thread to get through many patterns before running low on any single color.
At $17.99, it sits close to the $18.06 Hareline NB377 in this comparison and well above the $7.95 CDC28 and $3.95 elk hair options, though those alternatives are single-color, single-count materials rather than a 16-color thread set. The price gap makes more sense once the color range and total yardage are factored in.
The 4.2-star rating across 526 reviews matches the Hareline NB377 rating exactly, and both carry similarly large review counts in the 500-plus range. Where the two part ways is recent demand: the NB377 shows a bought-last-month figure of 50+, while this thread set currently reads 0+, suggesting its past reputation has not translated into the same current purchase activity.
Pros
- 16 colors in one purchase, avoiding separate single-color spool orders.
- 90 yards per spool provides substantial thread length for repeated tying sessions.
- 4.2-star rating across 526 reviews, matching the Hareline NB377's score on a similarly large review base.
- 3/0 nylon thread and a 33 line weight rating suit standard fly-tying technique.
- Priced at $17.99, close to the $18.06 Hareline NB377 while adding a full color range.
Cons
- Bought-last-month figure of 0+ signals little recent purchase momentum.
- At $17.99, it costs more than the $7.95 CDC28 or $3.95 elk hair single-count options.
- 0.22 pounds total weight is spread across 16 colors, meaning less thread per individual shade than a dedicated single-color spool.
- No stated target species or fly pattern recommendation in the listing specs.

Performance notes
The core numbers here are a 90-yard length, a 33 line weight, and 3/0 thread thickness spread across 16 colors, all in nylon. A 33 line weight paired with 3/0 thread points to a mid-weight thread suited to general fly-tying technique, the kind used across a range of pattern sizes rather than one built specifically for oversized saltwater flies or ultra-fine midge work. Splitting 90 yards and 0.22 pounds of total material across 16 separate colors means each individual color gets a smaller share of that yardage than a single-color 90-yard spool would provide, a tradeoff for variety over volume in any one shade. Compared to the Hareline alternatives in this comparison, which ship as single-color, low-count packages, this thread set is built for tiers who want to switch colors within a tying session rather than committing to one shade at a time.
What buyers say
A 4.2-star average across 526 reviews puts this thread set on equal footing with the Hareline NB377, which also holds 4.2 stars, on a comparably large review count of 550. Both products have clearly built a track record over time. Where they diverge is current activity: the NB377 shows a bought-last-month figure of 50+, while this 16-color thread set currently reads 0+, the same flat pattern seen on the smaller-count CDC28 and elk hair listings. That suggests steady historical satisfaction with this thread but a recent lull in new purchases relative to the one alternative still moving at volume.

Frequently asked questions
How many colors does this fly tying thread come in?

Is demand for this thread set currently strong?
Not at the moment. The bought-last-month figure reads 0+, while the Hareline NB377 in this comparison, which shares an identical 4.2-star rating, currently shows 50 or more units bought in the same period, suggesting stronger recent momentum for that alternative.
What line weight and thread size does this product use?
It is rated for a 33 line weight in 3/0 nylon thread, listed under Fly technique, which points to a general-purpose fly-tying thread rather than one built for a specific narrow niche like ultra-fine midge patterns or heavy saltwater rigging.
