Defective sleeves at a great price!! The glass bottles alone sell for $15 each, glass bottles with silicone sleeves sell for $44 brand new. This is a great way to try out BKR or their new Demi size. Offers accepted! READ: please be aware both sleeves have manufacturers defects. River the blue green color has a scuff on the outside and two small holes on the very bottom of the sleeve that go all the way through. River is sold out on the website. Dream the purple color has what appears to be air bubbles trapped in an area at the bottom of the sleeve. Both sleeves are still fully functional the glass is new and unused. See pictures for more information.
