Seal shelf drill holes

The holes have never bothered me, but instead of using those plug things, I would rather take the trouble to tape it over completely.. but you should make sure that the film is not too thin, otherwise you can still see the holes through it

The problem with the holes is that here - in the bedroom & kitchen - the moths like to feel comfortable in the wood and build their nests there.

We sealed the holes because of moths with simple tape - in all the Ikea cabinets. You can only see it if you look directly and with a knife, something pointed, etc., you can quite quickly change the pins when adjusting the shelves. The costs are also within limits.
