FS:SALIFERT TEST KIT - titration syringe replacements (numbers worn)

[Aquattro]

I also wash and dry with paper towel and never had that issue. Maybe it's oils on your hand, or salt water? Do you store them in the box?

Yes, all the kits are stored in the original boxes after everything is dried.

all the pieces are washed in ro/di water and my hands are thoroughly washed before i do anything in my tank. I generally dont have oily skin so i dont believe thats the issue but i'm only guessing.

all three of my syringes are worn and i have over half the test kits left (Atleast) for all three.
