Wanted - Api Test Tube

[Rio]

Bought a API liquid test kit for my brother for his birthday, wants to get into the hobby with a 200 litre tank. Was checking that the tubes were fine and the bottles had not been broached but one of my rabbits got a bit too curious about the test tubes and knocked one of them, resulting in a broken test tube.

Anyone got a spare one they would be willing to sell ?

I know I could get another 5ml test tube but wanted them to be the same as it is a present
