I am selling a set of 2 brand new, unopened blue underwater viewers for the beach, pool, sea, and river. I believe these can be used as underwater viewers in rivers and the sea. Since they have never been opened, please understand that there may be initial defects. I am not selling these individually. Although unused, please purchase only if you understand that they have been stored at home. I use recycled materials for shipping. Also, due to shipping costs, I do not use bubble wrap or other packaging. Please understand. Thank you.
