Using a disposable cup is unthrifty, because a disposable cup is used once and discarded. Also, it doesn't help the natural environment. However, it is difficult to store and carry a big and bulky glass or stainless cup. From now on, use a Pocket Cup. This is a new concept cup being foldable. Now we dont need to cut down any trees to make a disposable cup. You can use Pocket Cup conveniently like a disposable cup
which is environmentally friendly unlike a disposable cup, because it can be used continuously like
a glass or stainless cup.
