Thanks Gents, lots of handy hints there for the unwary first user of my soft soaps; I have trawled t'Interweb for hours looking for wider mouth suitable containers of 100 - 120ml capacity; thin to non existant on the ground. But I'm keeping looking, and have sent an enquiry of to a supplier. That's a nice scuttle, Rocketman.
Do any of you think aluminium tins (lined with a resin) and with a wider neck, would be a good idea? There are two things putting me off; one, that they only come with a wider neck in 150ml (I would prefer max 120ml), and the other that aluminium gets dented so easily, I think a lot of users would dent it with their big manly fingers.
For sure, every little knock will leave a dent. Of course, I could batter them up before sending them out and call it 'retro' or some such. So any thoughts you would have on types of containers would be very welcome.
