I once bought 100 pieces and 50 pieces once, because it should involve thicker and quality envelopes according to the description. Of course the envelopes serve their purpose, but I have very high quality thank you cards ordered on the Internet and looked plain envelopes, which should not look too cheap. And I would have more to pay attention to the weight of the paper, instead of thick and high quality to the words. There are normal 08/15 envelopes. In 1-shop around the corner I would like at the price of 50 pieces for 1 get (probably then Qualitatively but inferior, but note the price range)
