Beech wood is a strong hardwood with a high shock resistance. They have a beautiful and distinctive grain pattern with a slightly darker tone, each one is different in its own way. These are natural unfinished beads, however you can treat them with your favorite oil (olive oil, avocado oil, grape seed oil, etc.), local beeswax, or leave them untreated. Treating wood beads with oil or beeswax will help preserve them longer.
