Review on ZULU Studio Plastic Bottle Silicone by Matthew Goyette

So I bought it in March and I love it! It's a bit heavy, but it's a glass I've never used. The cap is easy to remove and snap on. The lock works well - there have rarely been problems with leaks when tipped on its side. The silicone cap inside has changed color slightly. A few months ago I washed it and found that there was a small oily stain inside so I washed it. I left it in soapy water to degrease it and it didn't come off! I used the brush and it just moved to a different place. I added dawn and hot water and then shook it. still not fat. So I just stopped using the bottle because I have no idea what it is. I also liked this bottle.
