Ugly container and useful strings

What can I do to this container cut out from a mineral water bottle, a plastic cover from a food can and some raffia strings I have been collecting?



I can use the container to store my keys but it looks awful and it is difficult for me to reach into the bottle to get the keys without hurting myself as the opening is sharp edged.



I decided to store the strings in the container. Then I placed the plastic cover over the strings before I placed the bunch of keys in.



That's more like a designer container in the making to keep for good.
