Anyone seen these flash cards as individual hiragana / katakana?

https://www.amazon.co.uk/Woifish-Japanese-Hiragana-Katakana-Syllabary/dp/B0CNZF9BK1/

Hiragana and Katakana separately?

With Japanese one side and English on the other? (Hopefully cheaper to)

I don't want an app, I want to learn it away from a phone or tablet (Mainly in bed at night).

I don't want the English on the same side as I want to check what I know and need to learn better.

I'm UK based.

Thanks in advance.
