I carry Miyuki and Toho seed beads as they are the most uniform round seed beads. Once you click on the color you like you can choose between sizes and quantity.

Colors can be hard when you want a specific look which is why I also offer 1 gram sample size bags, it's also helpful when you have a pattern that only needs one gram of five different colors. 

The top right corner of each photo will let you know what sizes that color is available in, so you don't have to click it first before finding out.
