the criteria is:
Brown colour rather than black
pref at boots and less than £5.44 as that is my points total and I'm having to budget 
Pref waterproof
I don't wear makeup very often, and nearly fell over looking at cheaper end brands in boots today (never got to the premium brands with the super all glam counters! I'd have probably vomited at the prices) It doesn't need to be a super dooper all singing ash re-enforcement big blow up super curly glam sort of mascara, just one that, er, well, makes your eyelashes look nicer?
