Carrom Association UK

Strikers, which are round and flat, should be no larger than 4.12 centimetres in diameter, and weigh at least 15 grammes.
You could win one of the strikers below if you come up with the winning caption for the previous post. They look beautiful, no? They are made from resin.
In the past, Carrom strikers were made from ivory. However, ivory has now been banned in tournaments and if you turn up to play with one you will be disqualified.
Metal strikers or ones containing a design in metal are not allowed either. They may damage the carrom pieces or scratch the surface of the board.
The striker can be one colour, or have a design as long as it is not offensive.
Some champions spend a lot of money to have a specific design engraved or hand painted on their strikers.
People become really attached to them, and some believe they win because they play with a lucky striker.
It must be much the same as snooker players who have a favourite cue.
It’s what you are used to, I suppose, and if you believe your game is better because of a particular piece of equipment, it probably is.
In the case of Carrom, just don’t lose your lucky striker.
