love this glue, it's the only thing that has worked to transfer the foils that have a clear/nonprinted area on them. i apply the glue in a thin layer, cure for 30 seconds, apply the foil to nail surface, rub over entire design with a cotton swab, remove plastic. the foil leaves a full transfer, not splotchy areas with half not sticking. the glue is undetectable under the top coat, even the areas that are not covered with the foil. will definitely reorder this product when i need more.
