KKCenterHK contacted me about a month ago to check out a product of theirs. They are an online shop based in Hong Kong that sell false eyelashes, nail and hair products. Since I never worked with foil before, I decided to choose their N.NAIL Green Diamond Hidden Nail Foil Transfer. They are sold for $7.69 for the foil and $12.00 for the foil and adhesive. There have 30 different foil patterns to choose from. Another favorite of mine is the Bubble Drop and Galaxy Diamond pattern.
The foil comes in a very long roll. It id 150 cm or 59" in length and 4 cm or 1.5" in width. If you're not wasteful with the product and use just the right amount, this roll of foil can easily cover more than 50 nails. The bottle that holds the foil adhesive is about 7 ml so this could last for a while as well.
