US Distributor of HB Electronic's LEDs - www.Buy-LEDs-Online.com
I ordered them from Buy-LEDs-Online, a US distributor for the well written about HB Electronics. HB Electronics is the recommended vendor of LEDs for LED Throwies and LED Floaties. They ship direct from China, but unfortunately they were out of stock on their throwie packs.
Buy-LEDs-Online helped me out by providing everything we needed with great phone and email support and super fast shipping.
Robert from Buy-LEDs-Online was not only very helpful, but said that he knew of Instructables and that he uses the site to determine what products he should carry.
So, if you're looking for LEDs for your next project, I highly recommend getting them from Buy-LEDs-Online.
