Two 500ml-1L water bottle nozzles for large dogs. I accidentally bought two sets with my family. One is brand new and unused. The other one was completely ignored, so it's practically unused. I've stored them at home, so I hope someone who understands this will purchase them. I will pack them disassembled in a Yu-Packet Plus box for shipping. The instructions are included, but the plastic case is not. Please note that the plastic water bottles are not included. *Individual sales are possible, but the set price is significantly discounted, so please understand.* - Brand: PETSTREET - Intended Use: For large dogs - Compatible Bottle Sizes: 500ml - 1L
