Stainless Steel Futon Clips (for Wide Futons) - Set of 6! For Drying Thick Futons

【Stainless Steel Futon Clips (for Wide Rails) - Set of 6
Supports Thick Futons for Drying】

These are stainless steel futon clips from Daiso, originally priced at 500 yen each.
I bought them because they were advertised to support rails up to 30 cm thick, but my balcony railing is exceptionally thick at 25 cm, and they wouldn't grip all the way to the back. They didn't fit...
I believe these are excellent products for standard-thickness balconies, so I hope someone can use them.

Used only once. I used 2 clips and removed the paper tags, but 4 are unused.
This is a set of 6.

Retail price: 500 yen x 6 = 3000 yen (3300 yen including tax)
