Kids these days don't know their strength and they are going to try and use those markers every which way they know how! But don't get surprised if you see that some of the DrawnBy: Marker nibs have suddenly gotten shorter while they were using them, there are solutions!We recommend that you use a pair of tweezers to pull out the nib and yank it out back into place! This should be enough to lock it back in position and start colouring again! The coloured part of the DrawnBy: Marker can also be separated from the rest of the body to access the nib if it has totally gone into the chamber, but this requires a fair bit of strength so we would only recommend this as a last resort.
