There are numerous finds of needle cases, and this needle case is modeled after how they generally appeared. One example is this discovery from Nacka in Södermanland: Link to the original.
The original was made of bronze and our replica is also made in bronze.
Here is another one from Gotland: Link to the original.
There is no lid, so the tube may have been closed with a wad of wool, or the needles may have been wrapped in a piece of fabric.
