Chillsner is the first and only in-bottle beer/drink chiller that keeps cold beer/drink cold from the first sip to the last whether drinking from the bottle or as you pour into a glass. Just freeze, insert into any bottled beer/drink, and drink right through the Chillsner. Made from stainless steel, Chillsner uses the same proprietary thermal gel as the famed Corkcicle.
My husband isn't a beer drinker but he is a glass bottle Mountain Dew drinker. The Chillsner works great for my husband and fits like a glove in the bottle. With having very hot and humid days the Chillsner keeps my husband drink chilled. My husband even uses the Chillsner in his plastic water bottle at work. This past weekend I even used the Chillsner to keep my pop cold while I was outside with everyone having a cookout. I like how easy the Chillsner is to clean and how fast they get cold in between uses. I highly recommend the Chillsner for keeping your drinks cold without watering them down.
