Are these common pencil case items allowed on a flight inside the EU?

I am going to fly from Italy (Venice) to the UK (London Heathrow) and back. Just today I started to think about the fact that the restrictions on liquids and "dangerous" materials might impact items that are quite common if taken literally.

I will carry a hand luggage, no checked luggage.

In particular, I was planning to bring my pencil case and I know a question has already been asked about ball pens (which technically do contain liquid):

Is it ok to bring a pen onto an international airplane (US to Pol)?

However, I would like to know about the following items:

Liquid paper / correction fluid (pen shaped) / Tipp Ex / Paper Mate / I do not really know the name in English... It has a label stating its volume (7ml), moreover it shows a warning sign as the liquid is considered flammable.

I know the regulations ban "paint" because it's flammable.
Highlighter: technically, this also contains liquid. It doesn't show a label with the volume.

Are these items allowed? Do they count as liquid containers and shall they be put in the transparent plastic bag and accounted for when verifying the volume limit?

Thank you.

Can I bring a pencil case on a plane?

The TSA states that it is ok to bring art supplies on a plane as long as they're not liquid or gel based over 3.4oz/100 ml. They also say that you should be able to take markers, crayons and pens (No to tactical pens) onto the flight with you without having them confiscated by airport security.

Can you travel with pencils?

That being said, whether or not your colored pencils make it through security could be up to a TSA agent. However, the general consensus among people who have traveled with colored pencils is they are allowed on a plane.
