Blu-ray BD-RE DL (Double Layer) Rewritable Discs, 6-Pack

I tried to dub today and found it was not supported.

Blu-ray Disc (Double Layer)
- Brand: maxell
- Model: BD-RE DL
- Capacity: 50GB
- Quantity: 6-disc pack
- Write Speed: 1-2x

It was not compatible with double layer.
When purchasing, please check if your Blu-ray player is compatible.

I have torn the packaging as I tried to read one disc.

There are 6 discs.
When shipping, I will send it so it can fit in a mailbox.
Thank you for your understanding.

It was around ¥2300 at Nojima.
