Hi everyone,

does anyone know where I can obtain these pots, I'm wondering whether
they've stopped making them?

According to their advert in the BCSS Journal, Malcolm Pym of Mega Pots
Ltd now manufactures and sells BEF pots.

I like the square ones for my cacti, they'll sit together with no wasted
space in between.

You could also try your local BCSS branch since they sometimes have
stocks of these good pots bought collectively in bulk for members.
