Copper and Titanium Set of 2. Please check the images for slight scratches on the Copper. Both are approximately 1cm square, so they are small. Element 29: Copper (Cu) Element 22: Titanium (Ti) Note: These are pure copper and pure titanium, but as they are made overseas, I cannot guarantee they are completely pure. Suitable for experiments or interior decoration. I cannot offer discounts on this item unless you purchase multiple items due to shipping costs.
