The goods came for less than a month. The ball meets the description. I bought different colors, because they have different stiffness.

The ball arrived in three and a half weeks! I did not even expect such fast delivery. Was well packed, not damaged. Doesn't smell like chemistry. I'm sorry only I got a black ball, it hurts dark. Well, he works perfectly. It is necessary only to wash it well, boil for a couple of seconds and can be used, as described by the seller in the manual. Gives a good load on chewing muscles, which means "angle of youth". If you do it constantly and do not be lazy, there will be results. I recommend all girls regardless of age. Seniors, especially. Good luck!
