This listing is for the inner sole only. For Longchamp Le Pliage S size. Made with 1.0mm thick PP sheet. (Matte or glossy finish, depending on stock availability.) Previously, I was selling 0.75mm thick ones, but I also separately offered the thicker 1.0mm ones on the same page, and they were well-received, so I've decided to offer them as a standard item. If you're concerned about the bag losing its shape when carrying heavy items, the 1.0mm thickness is recommended. (This is not a wooden or plastic board, so it will flex to some extent when weight is applied. Please be aware of this before purchasing.) ☆Currently, 0.75mm, 1.0mm, and 1.5mm thicknesses are available. Consider this as a medium thickness option. The size is made to fit my own bag (Longchamp Le Pliage S size, model number 1621, bottom size approximately 22 x 14 cm). Price has been adjusted due to the postal rate increase effective October 1, 2024.
