I bought mine from the Brother site but you can also find them at most office supply stores. I have never seen the colored labels in the stores. Most stores only carry the 1/2" tape but I prefer the 3/4" because I can get 3 lines on that size in a font which is easy to read. On occasion I will use the 1" tape but some of the label machines will not use 1".
Good luck. I love mine and wish I had started out with them. The tape will stick to any label but I prefer the ones I use because I can also write on the back side and keep the info in columns. The sale Charley has now is a very good price.
Can you understand why me kids say "Mom, you are sooooo organized"?
