Caused an Allergic Reaction!
While in theory these straws work just fine, you are putting your mouth directly on metal, which is not only uncomfortable when drinking something cold, but it caused an allergic reaction on my lips. I am allergic to nickel --which is usually not a problem in stainless stain-- but these must not be very high quality because my lips swelled up and I got contact dermatitis that took weeks to heal. If you are sensitive to nickel, beware!
