The thickness is about 5mm at the head, and the length is approximately 45mm. This is a set of 5 bamboo mekugi. I think they can be used for both shirasaya (plain wooden scabbard) and koshirae (sword mounting). However, since each shirasaya and koshirae has a different size, some adjustments may be necessary to fit perfectly. But from my experience, replacing or adjusting the mekugi often improves the looseness of the shirasaya and koshirae. Since ancient times, making mekugi has been said to be a skill of the samurai. Because it is a natural material, there are mekugi with darker and lighter colors.
