FerMonster™ Lid Opener

Got a stuck lid on your FerMonster™? Get it open much easier with this specially designed lid opener. It easily slides onto the lid and gives you comfortable hand grips to open a stuck lid.

FerMonster™ Carboys sold separately.

Note: We do not recommend using this tool to tighten the lid because the seal is made by the o-ring and not the pressure between the lid and neck.
