Advert for x2 : 4mm inner diameter rubber caps (not the white plastic part that is for demonstration purposes)

These are designed to fit where you would normally put a 4mm inner diameter tube but now want to block it off.

Generous 20mm length (Easy to cut if required, but having a little bit extra helps for removal)

Standard postage 2nd class, first class option available
