Are the valve cores removable?

No, the valve cores are not removable. These are the Presta Valves.

Where's my sticker? This is twice now I bought these tubes and when I get them guess what, no stickers.

I didn't get any stickers either....

How do u pump them up

I use a hand pump that can be used with either European or American valve stems.

Can this be used with 25mm tires or only 28?

I use these for my 25mm and 32 mm bike tires.
