Where is a good place to get cable marking heat shrink from?

I wanted to use the kind of stuff you see on decent looms when im making mine, so i can use yellow marking tags with either printed writing or even hand written before shrinking.

Either shrink tube labels or even just printed labels which i can use clear shrink tube over.

Only place i've seen so far is a bulk supplier and i dont need 2000 labels for one engine loom especially not for big money!

Cheers guys
