Stainless steel tea strainer/infuser because loose leaf tea is the way to go - higher quality tea leaves and less waste. Now more important than ever because so many tea bags contain plastic material, which sends microplastics into your mug when boiling water is poured over them. Make the switch to a stainless infuser. This one is big enough to brew a whole pot, but also fits in your favorite mug to make a single serving.
