The Kalita Wave heat resistant glass servers come in 2 sizes - 300ml and 500ml and fits perfectly with the Kalita Wave Dripper as well as other major stand alone drippers including Hario V60, Kono and Torch.
This server is perfect for me to use, which makes me easier to have a good experience.
Great little server to use.
Product quality is great. Fast delivery from kurasu. Thumbs up to their service.
