Small white rubber hole plugs

[VanFan]

Hello. Does anyone know where to buy the small rubber plugs that seem to fill every available hole in the GC, e.g. back of toilet door, down sides of gas cupboard door, the bottom of the two ‘garage’ boards? They seem to fall out really easily and then just left with holes.
Has anyone glued them or done something similar with success? Thanks.

You could try IKEA, I've bought different colours from there before, specifically for Pax wardrobes
