Not As Clear As I’d Like
These are entirely functional with easy-to-read gradations and caps that seem to fit snugly (I did not test watertightness). However, I had bought these for displaying an item inside the tubes and these are not entirely clear, but slightly opaque. This is not immediately apparent from the product photos which are on a white background, but on going back and looking more closely you can tell. If this doesn’t matter for your purposes, then consider this a five-star product. My only other comment is that the top shelf of the included rack could be a little higher, but at this price it’s hard to complain. You definitely get your money’s worth.
