A cuticle eraser of any kind is not something I would generally include in my beauty budget or spend any money at all on. But I must say this one is good and does work well.
You twist off the white cuticle eraser cap to reveal a flat pen-like applicator that contains a gold gel that exfoliates and moisturises the cuticles. Simply squeeze the tube and gently massage the cuticles with the liquid before pushing them back with the angled cap. It has a very fine grainy texture when applied to nails, so you have to wipe off and gel left on the nail surface before painting your nails. It definitely seems to help with nail strength. Worth the price of R99 if you have weak nails that break or split.
