A lenticular..the image changes as you move it around... cat playing a violin or fiddle on a big 1950s/60s purse. As you move the purse the image changes from a grinning cat to a cat with its eyes closed, lost in the appreciation of the music.. Look at the 3rd photo for a demonstration.
The purse is made of plastic, 17cm long and almost 10cm tall,  with a chrome top and a very satisfying snap shut clasp. Inside is a big and small compartment and another little zip shut compartment. The smaller compartment (behind the zipped one) see 4th photo - is just the right size for bank or credit cards.
I have several different colours
Apricot with white inside
Lilac with blue inside
Pink with pink inside
Green with green inside
Blue with blue inside
