Quick take

Fifty glass rattle inserts with steel balls that add audible attraction to soft plastic lures without requiring pilot holes.

This is a 50-piece set of clear glass rattle tubes, each 4mm by 16mm and holding two steel balls. They push into soft plastic baits such as worms and tubes without a pilot hole, adding a clicking chatter to the lure. A set this size covers many baits and leaves spares for replacements.

Best for

Upgrading soft worms with sound and vibration
Building custom jig lures
Murky water and low-light fishing

Skip if

You prefer silent lures
You fish clear water where fish spook from sound

Strengths

Two steel balls create loud chatter at any speed
No pilot hole needed; simply slide into soft plastic
50-pack sufficient for extensive lure building

Trade-offs

Glass tubes are fragile and can crack if mishandled
Not all soft plastics accommodate 4mm x 16mm size
Loud sound may spook fish in clear, pressured waters

Fishing fit

Water: Freshwater
Saltwater
Techniques: Jigging
