I've seen several posts asking for bento sources in the UK, so I thought that rather than replying with my tips individually, I'd do a quick round-up:
(1) The Japan Centre (goes without saying, really) - this is moving to Regent's Street next month. I find tJC a bit odd with some items only available online, some items only available instore, etc. But it's a great source for boxes, chopsticks w/case, forks and spoon sets, dividers, egg moulds, onigiri moulds, sauce bottles etc. continue reading...
Out of despiration and the fact that some conidments (mayo, syrup, furikake) don't fit in the cute but tiny sauce fish bottles, I rummaged through my spice cupboard hoping to find something of help today.
Lo! I found the lowly tiney tones sesame seed container! Peeled off the out side wrapper (just happened to peel off nicely). Wah - lah! Bigger condiment containers are now mine and locally availabe! And they can be used to pour, sprinkle or dip into!
Tones, I love y'all!
