1... 2... or even a dozen of rubberised balloons is fine for the chap with a inflatable lung... But not when you are having a event when you requires hundreds of these balloons by a certain timing!!!
An event company first approached me and I got them some models like those shown on the left. It works out well for them and now each 1 or 2 months,, they placed an order of 5 to 10 pieces with me to bring them in.
It is pretty simple to operate. Once you switched on the electrical supply of AC230V; there is these 2 blow tubes here which can be slightly depressed. You capped the balloon opening onto the tube, depressed it together with the feeling grips of your thumb and fingers, it activates the electric motor blower and air is blown up to inflate your balloon is a snap of less than 3 seconds... You have to be quick and agile to remove it once your desired balloon size is achieved. You will get a hang of it once you blew up a few of the balloons.
These are going now at $95 each... nett. You can get a discount if you are going to take from me regularly with a minimum order of 4 pieces like what this event organiser is doing. They are selling it as regularly as they had bought it from me... believing that they have a attractive margin too... I had not checked where and who is selling it locally and at what price???
