Equal broken

The retaining lugs on the "Telephone" are probably of very hard and brittle plastic. I feel after a few days the envelope with the phone in it, like slipped from his hand and placed on a table. Drop height vll. 20 cm. Here one of the retaining lugs as glass is broken. With a little tougher plastic that would probably not have happened. I bought so far no new envelope, because not exactly cheap. Annoys me but every time you open the envelope so, because I have to be extremely careful that the "mobile" does not fall out. So it makes no fun! Must seek me absolutely ne alternative.
