Due to timber being a natural product, you may see some variation in the grain and colour of the timber and between poles. Imperfections will not hinder their proper use.
Your long pole has been soaked in linseed oil for several months. When the surface of the timber seems dry, apply a generous layer of linseed oil to maintain its life and prevent cracking/splitting of the timber. Linseed oil is widely available at all hardware stores).
You may store the pole in the tube provided, or along the ground. Try not to lean the pole against a wall.
