This bottle stopper was designed for a Vodka company in Hawaii for their top-shelf package offer for 2018 and 2019. I have a about 20 in stock and will sell for cost. The top o-ring seals bottles with a 7/8″ opening (some top-shelf Bourbon) and the other o-rings are a bit larger than the SS-9000 stopper. They are all flat tops and stone or glass would be the best material for them but a strong epoxy would hold wood and metal also. Made from the same FDA food compliant 304 18-8 stainless steel. Lifetime guarantee on the stainless and the o-rings. Made and patented in the USA.
When these are gone, I will do custom runs but won’t keep them in stock. Fantastic Offer!
