Tragically thin, resulting in not being able to hold anything inside, tears easily with less than 1 kg.

Which durable & cheap ones from well-known brands in the supermarket.. it may seem silly but with 15-20 euros you have hundreds of bags for a year, which normally cost you twice as much - anyway you buy from elsewhere at a higher price-.

Small size, suitable for small amounts of bathroom waste. Quite durable, easy to tie from the top.
