In case anyone is looking for real seashells or starfish for any projects or anything I thought I'd pass along where I ordered from and had a great expereince!
the site is http://www.trs240.com/index.html
She has a ton of options and selection of shells and starfish, etc. Best of all she ships to Canada and shipping is totally reasonably priced at $4.50!
I purchased shells and mini starfish for our mini message in a bottle favours and theycame packed carefully so that none broke while in transit and they arrived super quick!
