This is a set of two inserts 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. I decided to sell them 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 inserts and L size inserts separately. These are handmade, so there may be slight variations, but they are finished within a practical range. The size is based on my own bag (Longchamp Le Pliage S size, model number 1621, bottom size approximately 22 x 14 cm). Just in case... the bag is not included in the product. Thank you.
