Keep your unfinished wine fresh! A silicone bottle hat is a very simple gadget that could save your bubbles. When the original cork simply won't fit back into the bottle, these silicone bottle stoppers come to the rescue. They extend the life of the noble drink and keep the flavors inside sealed for the next time the bottle is opened. The stopper is shaped like a gorgeous knitted beanie with a pom-pom on top to make the bottle look warm and cozy.
