【Unused】Yamatabi Dyneema Pillow Stacking Bag

This is a Dyneema Pillow from Yamato.
I purchased it in the summer of 2025 from an online shop for ¥6,490, but I ended up not using it, so I am listing it for sale.
I believe it can be used as both a pillow and a stacking bag for small items.

[Specifications]
Weight: 14g
Size: 20×33cm
Material: Dyneema® Composite Fabric 1.0
It is large enough to store your bath set for the return journey (underwear, socks, T-shirt, thin pants, towel).

Thank you for looking.
