Beer / Beverage Crate Label

We have had the problem that our beer, which we store in stacked crates, sometimes went past the use-by date because people were taking crates from the top, not knowing there was older stuff at the bottom. This is partly because you can't take out a bottle and check when there's 6 other crates on top.
This clip can be put onto the handle part of some brands' crates. It is designed for Beck's crates (slightly rounded top side to follow crate's curvature), but probably useful for other makes as well. It features an opening to insert paper tags with a date or whatever you want it to say inside. Of course, you can also use it for other things than beverage crates.
