Looking for A5 Tomoe River Grid Notebook

I haven’t been able to find my ideal notebook anywhere so I’m hoping you can help lead me to it or something similar:

• A5
• Softcover
• Tomoe River
• Grid (not dot grid)
• Lay flat
• At least 200 sheets (400 pages)
• Plain cover, basic designs and logo are ok but looking for something very ordinary looking.

C’mon Reddit don’t fail me now!

Update: Decided to go with the Sterling Ink A5 520 Page Grid Notebooks. It checked all the boxes for me and they just restocked today (24Jan2025) https://sterling-ink.com/collections/newly-restocked/products/a5-520-page-grid-notebooks-with-page-numbers-copy-temp-barcode
