Purchased in 2023. From Nishimatsuya, about 530 yen including tax. I wrote that I hoped to use them for playing in the river, but I kept forgetting to bring them every time we went camping, and they've become too small... It's a waste, so I'd like to sell them to someone at a low price! Since there will be shipping costs, I'll set the price to cover those costs. *Size* Labeled 13cm-15cm The following is quoted from the Nishimatsuya HP: ≪Color≫ Black ・For use in water or outdoors, such as the sea, rivers, pools, and camping. ・Soft cover that can be worn in the water.
