Pre formed pond (Cale Green SK3)

Hi, this is probably a long shot but here goes - my son and I wish to make a small pond in his first own garden and we would like a plastic pre formed pond liner if anyone has one available please. Any size from approximately 90 cm to 120 cm in length and 60 cm to 80 cm in width would be very welcome. I have transport and am able to collect.

Thanks for reading 🌸
