Norvise Aluminum Bobbin Spool – Package of 10
These precision-machined, aluminum bobbin spools are designed to fit the specified model. Many fly tiers use a variety of working threads and find it economical to simply change spools rather than maintain a separate bobbin for each thread. Each spool can hold between 50 to 500 yards of thread, depending on the thread size. It is best not to overfill them.

I bought these spools to switch between different thread types without buying new bobbins. The aluminum construction is lightweight and durable. They fit perfectly on my fly tier and hold the thread well without slipping. I’ve used them for several weeks and they’ve performed reliably.

The spools are easy to install and replace. I appreciate the variety in thread capacity. They’re a cost-effective solution for switching threads during fishing sessions. A little heavy to carry in a pocket, but that’s minor.

I’ve used these with multiple thread sizes and found them to be consistent in performance. The precision machining ensures a smooth thread feed. No issues with thread slippage or breakage so far.
