Japanese canteen holder strap and MINT pouch strap

This is a great condition canteen holder, the kind that ties across the neck of the canteen and also a mint condition strap of some sort. I am not sure what piece of gear that it was used for. Both items have markings on them. Please feel free to ask any questions before bidding. Oversease shipping will be via Japanese Post Express mail service which provides a tracking number for you. Thanks.
