To attach the anchor links of peak design

I can put them through the larger hole.
I could not get it through the top hole as the package photo.
The strap is sewn on the anchor links and cannot be removed.

This is available as an option if desired.
If you wish to order, I will send another invoice for the price of the peak design after order.

This time in Japan, the anchor links is JPY 8000.
The price seems to be a little back and forth depending on when I buy it.
