Commercial tea bags tend to contain low grade dust and fanning. Yes, they brew quickly, but they don't have the great aroma / flavour + the same level of health benefits as loose leaf tea does!
We believe loose leaf gives you better quality for your money as you're not wasting money on tea bag packaging that is thrown away + many loose leaf teas can be re-brewed!
Avoid plastic: square sealed tea bags nearly always contain plastic to heat seal the two surfaces of the paper tea bag together. The tea bag often contains plastic that is woven between the paper fibres to strengthen the tea bag. Typically these tea bags contain around 20 - 30% plastic. The premium silky pyramid tea bags are either made of nylon or plant based plastics.
