This listing is for a singlef brand new BOC branded standard non resettable flashback arrestor. The item you will receive is the exact make and model shown in the pictures. You will receive one oxygen / air arrestor plus an original copy of the instructions as shown. It is in perfect, brand new condition. If you look in my other items I also have a listing for both this and a fuel gas arrestor and for fuel gas arrestors separately. It will likely be posted as is in a bubble envelope. Just let me know if you require additional or alternative packaging.
