Hot glue in the form of sticks is used to fill the hot glue gun. As a rule, the glue sticks have a diameter of 7mm or 11mm. The thinner version is suitable for delicate craft work, such as model making. The 11mm variant, on the other hand, is preferred by DIYers who want to work on large areas. Most adhesive cartridges are transparent. However, they are also available in colored versions or with a glitter effect.
