Instead of the traditional style of mascara, which could be compared to painting lashes, tubing mascara is made of polymers that form around your lashes, almost like a jacket. 

Each of the tubes that forms around your lashes remains completely intact once it has dried, and that includes when you're washing your face.

The Sturm kits are brilliant value with great travel sizes to try and a full routine including cleanser, serum, moisturizer, etc. The bags are also great–the study canvas means they last really well and can be properly washed.
