Vintage Salt & Pepper Condiments

A pair of original, Retro, Vintage Salt & Pepper Condiments, I think they are from the 1970s era.
I don't believe they have ever been used. There is a tiny nick to the bottom of one of them. They are not damaged, as it was done pre glaze as there's glaze in it.
I don’t believe the plastic stoppers have ever been removed. They have a patent number of 439063 & are made in Endland.
Please let me know if you know the pottery. Thanks.
A great trendy design & look.
Approx just over 2 1/2" tall.
Please study the images.
