Avon and Somerset Police are warning that fireworks stolen from a property in Langford on Monday night can be lethal if used by members of the public.
The makes that were stolen are listed as Category 4 under the Fireworks Act 2003, which restricts their sale to fireworks professionals.
Police say they do not have a fuse and would explode immediately if someone tried to light them.
Others are designed to be lit within a metal tube to control their direction.
Around 100 fireworks were taken including Purple Tiger Tails, Red Tiger Tails, Spinning Flower Rings and Xette Ring Cyler shells.
