Volx Japan RO Water Purifier Actas RO500G I purchased this for shrimp breeding, but I never used it and have been storing it. There is a hole in the cardboard box, but I will pack it securely for shipping! This is a new, unused item! I believe it works fine, but please understand that there is no warranty if it is defective. Please comment if you have any questions! Shipping will be at the buyer's expense, but if you would like it to include shipping, please let me know your region and I will calculate the shipping cost and adjust the price to include it!
