I had used this product previously. The one pot I had lasted for 2 years at least. I was dubious that I could get a replacement so I was really happy to find it on the Nail Supply UK website at a really reasonable price. The product itself is a pink paste which you spread on your natural nails and buff up ( I personally use a microfibre cloth). It gives a brilliant natrual shine and over time will get rid of grooves in the nail. You don't use a lot, just a smearing really so a pot really does last quite a long time. The shine itself last a long time, and using about once a week is adequate, I think. NailSupply UK sent out the parcel in a timely manner and it was well packaged. I am very happy to recommend both the product and NailSupply UK. Thank you.
