Fundoshi loincloth, new, 7 pieces

This item is new and unused, but please understand that it has been stored at home for a long time before purchasing.

The fabric is almost pure white, but upon close inspection, there are very small stains due to long-term storage. (These are not dirt-like stains.)
Purchased in Ise, where the Isuzu River flows.
How about for training or festivals?

I opened one item to check.
While I cannot guarantee the condition of all items, the exterior is clean.
