Will these tubes fit?

Decided I'd better stock up on some spare tubes for the new bike and would like Slime (I know a lot of people on here hate them, but I think they are great and have saved me from loads of punctures on the mountain bike.

Now the slime tubes state 700x19-25, my tyres say 700x23C. If they just said 700x23, I would assume they will fit, but what (if anything) does the C mean?

They'll be fine.

Take no notice of the people who poo-poo slime tubes.

I had a trail motorbike. I gave it a dose of OKO ( slime in the seventies ) and after a Sunday morning's X country, found seven thorns in the rear tyre.
When I pulled them out, a small bubble of green ooze appeared, but quickly stopped when the gas route was sealed.

I have Bike Doctor X in my non-kevlar tyres now.

BTW. Slime does NOT stop punctures. It stops the air escaping when you get a puncture. You still have to patch the tube.
Regularly inspect the tyre tread for small bubbles of green 'snot'

They will fit fine, but i would check how heavy they are before fitting. An extra 200g of spinning weight will make your bike feel very different.
