I did not buy this version "sport" with lobster but the older version which was called "aqua", without the carabiner and punctures, but they are exactly the same resistant plastic cards to water and stains . Very good idea to take the game on vacation, play in the grass, on the beach, the cards are not damaged, do not honk, did not score (no possible cheating by tracking individual defects of wear!) I highly recommend this release "all terrain" to the classic version of cardboard, especially the little ones can play without difficulty and are often a bit awkward ... No need to wait until the age of 7, however, for from 5 years old, the children quickly learned how to play with the cards 0-9 and the symbols and colors! A classic to have at home.
