It's pretty easy to use them. Inside there is a glass flask in which you put the tea leaves. Then you fill it with boiling water, light a candle on a special stand, put a teapot, and let it brew a little. The teapots have a comfortable shape. I don't remember
a single time that I poured tea on a tablecloth. It is also convenient to wash them, just throw the tea leaves out of the flask and rinse with water.
The candles burn for about 4 hours, which is quite enough for tea drinking.
The seller says that the teapot is made of durable glass and can be used on the stove and for coffee, but I never used it like that.
Over time, I bought additional cups, spoons, sugar-bowl, jars, tea. All these items are perfectly combined and I will write about them below in the "Useful Information" section.
P.S. If you have any products that will complement my collection, please share them in the "Useful Information" section. Enjoy your tea.
