It is hard to get off just like every glitter filled polish. i suggest letting your nails soak in a bowl of remover; if you can use acetone. it is harsher and needs to be used in a well ventilated room but it was cut the work in half. if polish is still stubborn use a file/buffer to get remaining flakes off nail. ALWAYS use a base coat with glitter polishes, will also help with the removal process!
Yes it can be hard to get off...tip use an old polish you don't like, but a think coat on your nail, wait about 30-45 seconds and wipe off. It gets a LOT of the glitter off and makes removal much eaiser for me.
