I've seen two boxes in Waitrose I'm tempted by, but they're relatively pricey. One has wind-up plastic animals in them, all different - £10 for 6. The other has the usual wine stopper, photo frame, etc, but better quality than most - £20 for 6. We have difficult MIL to please and two kids, aged 8 and 12. I know it would be better to fill my own (fill-your-own ones also on sale in Waitrose), but that means shopping (sigh) for small stuff.
What have you bought? Any good?
