This is the thing to buy to win favours from friends and family.

Nestle Japan has collaborated with famous sponge cake brand Tokyo Banana for the second time to come up with Tokyo Banana Kit Kats.

This time round, however, a special ingredient is added to the snack -- feuilletine, the broken down form of crisp crepes.

Here are some photos of the product:

The Tokyo Banana Kit Kat consists of wafers layered with banana and spiced caramel cream, a banana-milk flavoured white chocolate coating, and feuilletine throughout this coating.

Unfortunately, the limited edition item is only available from now till January 8, 2019, at the Daimaru Department Store directly connected to Tokyo Station in Tokyo.

A box of eight goes for 680 yen (S$8.32) while a box of 15 costs 1,250 yen (S$15.30).

And as if its exclusivity isn't daunting enough, the collaborative item will only be available at that spot from now till Jan. 8, 2019.

The product will also be available at Haneda Airport in Tokyo from December 26, and at other stores around Tokyo, including JR Tokyo Station and Tokyo Solamachi (at the base of Tokyo Skytree), from January 9.

How to buy from Singapore

If you're not going to Japan, or have no friends heading there, you can get them from Airfrov from S$19 for six pieces, or S$29 for 15 pieces.

Remember to select the "premium" option, and do not confuse with it with the first collaboration, which looks like this:
