We carry professional grade drafting tape, and drafting dots. Alvin brand drafting tape has been a mainstay in the drafting professional and within drafting classrooms all over. It's a personal preference if you rather use drafting dots or drafting tape. Drafting dots are just pre-made round shaped pieces of masking tape that make it convenient since you don't have to cut or rip the rolled drafting tape. However, sometimes one dot is not enough on a large drawing and you may find that you prefer to use regular drafting tape so you can pull off and use as much as needed. Drafting tape is similar to masking tape, however it is not as sticky and does not tear your drawing or artwork when you remove the tape. It's sticky enough to hold a drawing down but not sticky enough to ruin the media you are using it to hold down.
