Saw this posted by a few sources on Twitter and looks good for a fair bit of work on set. You will still need to have full size rolls of GAFFA around though, but microGAFFER will be a handy roll of tape to have in your kit. microGAFFER rolls are just 2.5 cm / 1 inch wide by 7.3 Meters / 8 yards long and weigh 62 grams / 2.2 ounces. Standard gaffer tape is 5 cm / 2 inches wide by 54.8 Meters / 60 yards long and weighs 901 grams / 2 pounds. microGAFFER is also available in fluorescent colours!
