Slider design is a thin elastic film with an image applied to paper (paper for easy storage and transportation). This method of decorating nails is very simple, but the effect is unique. Thanks to the huge variety of colors and designs, with the help of slider design, you can create a wide variety of nail art without much effort. When applied correctly, this design is quite stable.											47.00000000	510M	3906	LILLYSHOP	21	slayder-dizayn-tm-1294-en	406/510	D
