Our colorful soft gel nail stickers set is designed with ethanol and glycerin. The usage method is extremely convenient: Use a wooden stick to polish the nails and remove the dead skin around. Use alcohol wipes to clean the dust, grease or dead skin on the nail surface. Keep it dry. Use the nail stickers to match your nails. It is recommended to choose a sticker that is just the right size or slightly smaller. Tear off the nail sticker and stick it on the nail surface, close to the base of the nail. Avoid sticking it directly on the skin. The sticker should be evenly applied without any wrinkles or bubbles. Use a sharpening rod to remove the excess nail material along the edge of the nail. Keep the sharpening rod at a 90-degree angle; do not rub back and forth or left and right as this will affect the effect. Avoid touching the nail sticker to water within 2 hours to prevent it from getting sticky. And it can be waterproof for 21 days, applicable daily.
