Failed Item Colorgram Shading Creation Liner 01 20% Shading

My personal failed purchase is the <Colorgram Shading Creation Liner 01 20% Shading>! I bought this product at Olive Young last year to create aegyo sal (under-eye bags).

At first, the original light brown color came out well, but as time went on, the brush dried out quickly, so I can't use it now. Above all, the staying power is poor. It washes off immediately if exposed to water or sweat. I consider it a relief that it is an affordable product.
