Overview
A white fly tying material from Hareline, packaged as a single 0.25 ounce unit under the model number NB377, sized to top off an existing tying kit.
The listing carries no material description beyond color and weight, and Hareline sells a wide range of tying components under similar model numbers, from dubbing to synthetic fibers. Buyers should confirm with the seller exactly which material NB377 refers to before ordering, since this data set does not specify fiber type.
- 0.25 ounce package weight
- White color
- Single piece count
- Hareline branded fly tying material
Who it's for
Fits fly tiers who already know Hareline's NB377 product from past purchases or a supply list. Not a safe pick for someone needing a specific confirmed material type, since that detail is missing here.
Strengths and trade-offs
Drawn from this product's published specifications.
- From an established fly tying materials brand
- Compact size fits into an existing tying kit
- Material type not specified beyond color and weight
- No description or reviews to confirm what is in the package
Performance notes
As a small 0.25 ounce package, it is sized for topping up a tying kit rather than stocking a full production run of flies.
