bottles-jars White Shrink Capsules?

Anyone know of a source for white shrink capsules or bands that actually look decent?
I got these off Amazon to try out, and they shrink uneven and look like garbage on a 5oz. woozy bottle.

My labels are white, and I’m trying to find a match for a cleaner look.

Shipping packaging is different than bottle labels and shrink bands. While both do affect percieved professionalism, i want to get get back to that little contest Hellfire started.
