Nikon PK-13 Extension Tube

This is a thick extension tube for Nikon.
When attached and used for shooting subjects like flowers, it offers an interesting depiction different from that of a macro lens.
It shows some signs of use, but is in good condition with no major noticeable scratches.
As it is priced affordably and is inherently a durable item, it will be wrapped in bubble wrap and sent via Yu-Packet Post Mini. Please note that it will be sent in an envelope.
If you wish for it to be sent via Yu-Packet Plus (box), please comment before purchasing. An additional charge of 340 yen for the shipping difference will be applied.

I am listing this on behalf of the grandmother of a friend's photography store (which has since closed). This was used for copying and other purposes at the store.
