I have a few flasks, but none feature a transparent window that shows me how much alcohol I have left. When I saw Ragproper’s Modern Glass Flask, I knew I had to have it.

One of the plus sides of a glass flask is flavor preservation. This If you have used a metal flask for any length of time, you may have noticed that after a while, you can taste a hint of metallic flavoring. You won’t have to worry about that with the Ragproper. The glass flask does not compromise the alcohol’s flavor integrity whatsoever.

About Ragproper:

After a terrible experience drinking forgotten whiskey from a metal flask we scoured the internet in search of a glass flask, and could only find these relics from the golden age of flasks. Hence, we began our quest to design the modern glass flask and bring quality drink-ware to those who love their precious spirits.

Ragproper the name was formally used in old western slang meaning dress well, aka (gentleman). Although not used today, we thought we would bring back the old lingo.
