This is a sale of the inner sole only. For Longchamp Le Pliage L size. Uses 1.0mm thick PP sheet (Matte or glossy finish, will vary depending on stock.) Previously, I was selling 0.75mm thick ones, but I received good feedback on the thicker 1.0mm thick ones, which I was offering separately on the same page, so I have decided to offer them as a standard item. If you are concerned about the bag losing its shape when you put heavy items in it, I recommend the 1.0mm thickness. (This is not a wooden or plastic board, so it will bend to some extent when weight is applied. Please understand this before purchasing.) ☆Currently, 0.75mm, 1.0mm, and 1.5mm thicknesses are available. Please consider this as an intermediate thickness. The size is made to fit my bag (Longchamp Le Pliage L size, model number 1899, bottom size approximately 30 x 19cm). As this is handmade, there may be slight deviations, but it is finished within a practical range. Also, there may be linear scratches that appear to have been made during the PP material creation process. Thank you for your understanding.
