SALES INCENTIVE TRACKING DEVICE

[echokilo]

I need to track a work sales incentive and have had the idea of putting a ping pong ball in a tube for each sale made ............. in the It's a Knock Out style for those of you who remember ................. ping pong balls are not a problem, but where can I get lengths of tubing the right size (38/40mm) with either a "foot" to stand it up with or an end cap so we can wall mount them with velcro? TIA

38-40mm- I assume that's the diameter.
I assuem you want clear plastic that you can see through.
Maybe a petshop will sell them - i recall seeing some for hamsters to run through
