Similar, but made with wood and nails, which makes way more sense for a knitting aid. Much cheaper and easier to produce.

Also, the dodecahedrons are found in sizes ranging from "4 to 11 cm" in size (according to Wikipedia). That _might_ make sense if there were specialized ones for everything from kids to very large adults, but then...why aren't they found in clusters? You'd expect some towns in the Roman Empire, where gloves were made, to be full of them (in sets, not individual pieces). Instead, they turn up individually and fairly randomly throughout much of the Empire. They often turn up in coin hoards, too, which is an odd place to store a glove-making doodad.

Clothing production in historical contexts (including Roman) is usually a household activity. This mostly means it's done by women of all classes, if only perhaps as a show of virtue. A glove-making device, as a personal item, might show up randomly any place they were used.

Conspicuously expensive household items would also not be unknown. It makes some sense that the bronze survivors may be those owned by wealthy women, where the bulk of those used may be (unlikely to survive) wood.

Compare to needle cases, which were similar womens' tools. Most of them were wooden or bone, but rich women would get fancy ones made of bronze, and pretty commonly be buried with them.
