Chopsticks are the most important item of cutlery in Japanese and other types of East Asian cuisine, so it is important to know the main differences from pair to pair. Long chopsticks (over 30cm in length) are best used for cooking and serving. Shorter chopsticks (around 20-23cm long) are standard chopsticks used at home. Chopsticks that are shorter still and come in chopstick cases are for packing in your bag and taking to work or school. Take a look at japancentre.com's entire Chopsticks & Cutlery range.
