"We have bought the coffee one-way degassing valve in the local market in Vietnam,I don’t like the quality of the coffee valve in the local market,because it will become the two-way degassing valve at last.After I know Hebe Mai from Wojin One-way degassing valve from Facebook,she let me know what is real coffee one-way degassing valve.I am a roaster,I love roast coffee bean very much,but I face a important problem: how to keep the coffee fresh,release the co2 and prevent the air get into the coffee bag.Before I bought the Wojin Coffee One-way degassing valve,I am using the local coffee valve,that make me very upset the quality of my coffee.But now,Wojin help me solve the problem and keep my coffee fresh after I roasted it and transport to my client.Thanks for Wojin Coffee One-way degassing valve."
