I received this from my family who used it several decades ago, but I'm not using it, so I'm putting it up for sale. I'm a novice when it comes to diving, so I don't know the details, but the black part is torn and detached, and I think there's a feeling of use and some deterioration. I have washed it with water. Blue silicone snorkel, Tabata Marine Sports model. Diameter: Approximately 40cm - Brand: Tabata - Model Name: Marine Sports - Color: Blue - Material: Silicone Bundling with other items is also possible! #Surfing #SEA #Ocean #Diving #MarineSports
