I've been using Kuhn Rikon decorating bottles but find they are very hard to clean and only hold 2-4 oz of icing. I ran across these on several cookie decorator blogs...so I was anxious to try them. Bottles run about $2.49 a piece or you can buy in a set of 3 for $5.49. I bought a few 8 oz. & a few 2 oz. to see how I like them. All standard tips fit the bottles. The small 2 oz. bottles come with a cap so you can store your icing airtight. I like this feature. The Kuhn Rikon caps tend to fall off and don't really seem airtight to me.
2 oz. bottle caps
2 oz. bottle
bottle couplers .. works with any standard size decorating tip
I'll do another post letting you know how I like the CK bottles... hopefully in the next few days
