Thunder B TB-S-04 Dumbbell Replacement Shells (12 Pack)

Thunder B TB-S-04 Dumbbell Replacement Shells (12 Pack)

Keep your Thunder B Sonic Grenade ready for action with these genuine Hakkotsu TB-S-04 Dumbbell Replacement Shells. Supplied as a pack of 12, these disposable plastic shells are designed for use with a compatible Thunder B reusable core, allowing you to quickly reload your Thunder B after each activation.

How the Thunder B System Works

The Thunder B system consists of three main components: a reusable core, a disposable plastic shell and a standard 12g CO₂ cartridge (sold separately unless stated). Once assembled, the reusable core stores the compressed CO₂ inside the shell. When the safety pin is removed and the spoon is released, the timer activates before the shell ruptures, rapidly releasing the compressed CO₂ to produce the distinctive Thunder B report. After use, simply replace the spent shell, install a fresh 12g CO₂ cartridge and the reusable core is ready for your next game.

Compatibility Notice

These TB-S-04 replacement shells are designed for the standard hand-thrown Thunder B Sonic Grenade system. They are not compatible with the Thunder B Shocker (Tripwire Mine) system. If you require replacement shells for the Thunder B Shocker, please see the TB-S-05 Shocker / Tripwire Replacement Shells.

Manufactured from lightweight plastic, each shell is designed for single use and ruptures upon activation to produce the signature Thunder B sound effect. Simply screw a fresh shell onto your compatible Thunder B reusable core, fit a new 12g CO₂ cartridge, and you're ready for your next game.
