ガラスなので劣化が少ない。内容量が見える。

If you’re looking for a glass flask this is a pretty good one, but you’re probably better off with a steel flask. This thing is pretty weighty and that really has prevented me from using it as much as I planned. This is fine tho as it gets used for overnight trips and would probably be a good addition to a golf bag. The material quality is excellent and it came in a gift quality box.

I haven't had much luck with flasks but based on what I was seeing in online reviews about the Ragproper ones, I bought one. For $28, it feels very solid and is good quality. You don't have to worry about a metal taste with the stainless steel ones. The only "bad" thing I noticed was that there were little specks of something white in the flask all along the glass so I had to wash it a few times with a silicone straw cleaner to get rid of it. Not sure what it was, but be sure to clean it before you use it. Edit: after the flask dried from cleaning it, the inside of it was already scratched up from the brush I used to clean the specks off the glass.

Perfect product, best costumer service.

Very nice little pocket flask- thickness and weight of glass is good, top is high quality and seals properly, and the silicone sleeve fits snuggly. One concern I had when ordering was the quality/thickness/texture of the silicone sleeve… I was curious if the texture would be smooth or grippy, and wondered if it would transfer in and out of clothing pockets easily, or be a pain to retrieve/stick to the inner pocket fabric…. The silicone sleeve has a smooth surface, and does not cling to your clothing fabric/pocket- win! I like this flask so much that I believe I will purchase one of the leather wrapped versions-
