Pro Drop weight
Metal inserts that are used both as weight and as the body of the tube flies. Very easy to use.
With a couple of hackles, a little flash and some wing material it is easy to quickly tie a stack of beautiful and well-fishing flies with the Pro Bulletweight. Mount on the Pro plastic tube with a little glue.
In particular, sizes Xs and S are widely used for sea trout and salmon, this is the right weight for the fraceasy fly, which Daniel fishes with a lot.
