I'm so happy that this markers hack works! I saw this artroom hack some time ago and I thought I should try it too. It's too silly to worry over the lost of markers' covers or duplicate colours in a set. Sometimes, you have the whole set dropped on the ground and the markers seem to have a mind of their own. They can roll under the children's giant Smiggle lunchbox or fall into their school bags.
Despite all my tellings, you just have that set of markers that are not in place and you can spot them miles away but no time to fix. I removed all the unnecessary packagings and secure them with Duck Tape (not kidding, that's the brand). It's also easier to sanitise this way. The neon tapes are so brilliant and blinding no children can miss returning.
Just a word of caution, you can't cut the tape with scissors as the adhesive is too strong. NO MORE MISSING MARKERS! YAYY!
