This is a set of two inner soles for the Longchamp Le Pliage S size bag. These are handmade items. My specialty is woodworking, but I made these at my daughter's request, and they were well-received. Now, both of my daughters and my wife use them regularly. I decided to offer them for sale so that everyone can use them. The material is 0.75mm thick, milky white PP sheet. (Matte or glossy finish, depending on stock availability.) The corners are rounded to prevent scratches on the bag. This set of two is for those who regularly carry heavy items. ● When used together, they are equivalent to 1.5mm thickness. They fit within the edge of the bottom seam, so they won't shift. (Of course, you can also use them individually.) I also sell single pieces and L size versions separately. These are handmade, so there may be slight imperfections, but they are finished to a practical standard. The size is based on my own bag (Longchamp Le Pliage S size, model number 1621, bottom size approximately 22 x 14 cm). Just to be clear... the bag is not included. Thank you. Instant purchase is OK.
