Whats the name of this.....?

When I was younger (about 20 years ago!) there were these little pots of liquid plastic in clear bottles that you could use to decorate t-shirts/fabric. If I remember rightly, you could also use them on plastic, mirror and gl. They came in a whole range of colours and the bottles were about the size of nail varnish bottles but made of plastic not gl. You turned the bottles upside down and squeezed slightly and the thick liquid would come out through a hole in the top. You could draw or write with them. After a few hours, the liquid would set and you could wash the t-shirt and the design would stay. It gave a raised/3d effect. Can anyone remember the brand name/make of what I'm talking about? Thank you!
