I can’t believe you’re not going to buy one of these:
Anyway, glad you’ve discovered there’s a local shop where you can buy this shit.
What I would say is that I bought a £1 one and it’s really weak plastic and hard to move around when it’s more than about a 1/3 full, so I’d probably go for a £3 proper Addis one.
What are you going to be using this bowl for? If it’s just for washing up, then probably the £1 is fine but if you’ll be using it for window washing and stuff around the house, make sure it isn’t at all bendy.
