※ We offer significant discounts on driftwood when you purchase multiple items, so please feel free to inquire. These are natural driftwood pieces collected from the sea in Izu. They have only been brushed and sun-dried; no tannin removal or sinking tests have been performed. Please use them in aquariums, etc., at your own discretion. Use them as materials for aquariums, terrariums, gardening, crafts, and DIY projects.
