Thank you for looking. This is a lid for a French military canteen cup. The canteen cup shown in the photos is not included in this listing. The material is 1mm aluminum. This was made to fit the canteen cup I own. Depending on individual differences in canteen cups, the fit may vary slightly. You can choose between a triangular or round handle (see 5th photo). Please let me know which you prefer via message after purchase. If no message is received, I will send one of the available handles. Please consider that there may be scratches from the manufacturing process. Shipping will be via YuYu Mercari便. It may be changed to RakuRaku Mercari便. If you have any questions about dimensions or anything else, please ask in the comments. Returns are not accepted after purchase! Please only purchase if you understand this.
