Pink & yellow pulled loop modern studio art glass spherical vase & some magic buttons

Continuing my pink & yellow glass theme, here is a cute little piece of modern studio art glass which I purchased in an op shop just over 20 years ago. Sadly it is unsigned, but maybe someone might recognise it. Since it turned up second hand in 1999, I guesstimate that could date from the 1980s, & it is most likely by an Australian artist.
It is fairly thick cased glass...clear over a particularly nice shade of pink with a simple, yellow pulled loop decoration, measuring around 9.5 cm tall. Maybe it once had a stopper & was intended as a scent bottle, or perhaps it always was just a small, spherical vase. As can be seen it has a rough, snapped pontil mark which is also a little burnt - looking (no, that's not dirt).
Fourth photo shows some more pink & yellow goodness - five glass buttons, which I believe to be of Bohemian/Czech origin & dating from the early 20th century. A pleasing & cheerful colour combination!
