After countless of trial and error, the best tool to create the holo chrome nails are the sponge applicator! It picks up the right amount of products and help distributes the powder nice and evenly. Product details: Dual end sponge Hold product very well and help reduce wastage High quality, dense sponge Round shape for easy application Reusable Easy to clean Cleaning tips: To reuse, simply tap off the holo powder and wash it with clear water. Wring out the excess water by gently squeezing the sponge with your hand, then use a clean, dry paper towel to absorb any excess water within the sponge. If the sponge is still damp after you blot out the water with paper towels, let it sit in a dry location to continue air drying in a room temperature. Wait until the sponge is completely dry before using it again. Shop Holo LED Lamp here. Shipping advisory: We do not recommend buying the sponge tool on it's own as the shipping fee is much higher if it doesn't ship together with other items. We highly recommend purchasing the tool with at least one nail polish to even out the shipping fee.
