These are amazing! I could not locate an artist mark. The "seaweed" is fairly flexible so you could likely adapt the sculptures as needed. I don't know if they were originally designed as functional art, but I think they would look amazing with glass candle holders in the middle. They are handmade so they are 'perfectly imperfect'. They are also not the same exact shape or size. Keep all of this in mind if you decide to bid on these. If the shipping ends up being less, I will refund you the difference. Please refer to photos and let me know if you have any questions.
