### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    good solid flask
  

*by R***D on Reviewed in the United Kingdom on 3 October 2023*

This is very sturdy, good quality glassware and I am confident it will survive for many years of brewing, perfect for making up yeast starters.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Great for making yeast starter
  

*by J***R on Reviewed in the United Kingdom on 28 December 2023*

Arrived well packaged inside a bubble wrap bag and cardboard box.I'm using it with a magnetic stir plate to make yeast starters for my homebrew.  Most brewers use a 2l conical flask for their starters but I decided the 1l was sufficient for the styles of beer I brew.  Very happy with my purchase so far.  Hopefully it will last me many years.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Excellent
  

*by J***  on Reviewed in the United Kingdom on 15 October 2022*

Very quick delivery,  and a quality item.
