ᐅ Looking for the name of IKEA drinking glasses from 1999/2000

Hello

I have IKEA drinking glasses at home from 1999/2000. They hold about 3.5 dl (12 fl oz) and have a classic shape: round, slightly flaring towards the top, about 10 cm (4 inches) high, with a base diameter of about 6 cm (2.5 inches) and a top diameter of about 8 cm (3 inches).
What stands out are the decorative grooves running parallel to the base, spaced about 0.5 cm (0.2 inches) apart, i.e. horizontally.
The glass surface feels smooth, as the grooves are inside the glass.

Does anyone know these glasses? I am looking for replacements.
What were they called?
Does anyone know if it is possible to get old IKEA glasses?

Thank you very much for your help and best regards

Hello,
these should be the Sisu glasses.
They are occasionally offered on eBay.
