purchase bottle openers and bar supplies

I am looking for a tap cap bottle opener,a cylinder approximately
3 1/2 inches tall and 2 inches across .You set unit on bottle to open press downward it pops off cap .The bottom usually has a magnet which keeps cap from droping on floor .These are usually used for beer soda and water wit a regular metal cap.
I am needing a supplier on a regular basis I have seen these units in many colors however I am interested in a white plastic only. At this time we will do printing for outside graphics here in the USA .Please contact me with any info.

Thanks
Jennifer
