My earwax dry one

The yellow yellow stain is the yellow ink from a printer. That rubber cap is from a printer modified with the continous ink flow system...

Meaning, it's a very small rubber plug?? if it's small cavity you need to seal, can try using those rubber for tire repair, ie, push in pull out to seal.. or is the cavity big enough for an ear plug??

Children Bath Tub?

This can be bought from Kaki Bukit toys and children shop ( Beside shun Li industrial building). If i am correct, this is the stopper for the children bath tub. Last time I bought it, around $5 ( very expensive )

Just in case anyone is interested, the rubber cap can be found at inksg or sginkstation or something like that at sim lim square. 4 for 1$.
