Can anyone help me decipher what bike tyres to order from these photos??

Trying to be nice and surprise DH with new bike tyres so he can have a distraction, I’ve got these numbers, but how do they relate to what tyres i actually need? Is it really simple?

700 x 35C is the tyre size.

If you want an equivalent tyre, something like this would do (just be sure to select the 35 option)

Thanks @PinkingScissors and @YetAnotherUser
and I meant to write inner tubes not tyres! But ordered thank you 😊
