As Kontaktlinserträgerin I find it super convenient to always have a container here, so I can, if necessary, remove the lenses. This container I ordered as my "on the road" back up and am very satisfied. He has two colored container jar which is quite handy if you want to distinguish between left and right. Although this is not the case with me, because I wear a uniform thickness in both eyes, but this marshmallow colors in pink and white are an eye-catcher. So when I grab my purse, this small container along with a small bottle of contact lens solution always. The delivery came in a small envelope, which fits easily in the mailbox on the second day of my order. When the price of one euro, I can also recommend all lens wearers, often times to change the container to prevent infections. I'm going to these containers regularly order again.
