"This is a very cool idea, but it's currently only available to fit 12mm tape. In the USA, it's much more common to see 1/2" or 3/4" tape, making this mostly unusable unless a version with wider internal dimensions is made available.3/4" might actually be the most useful width for this. In addition to (wide) Scotch tape, it would be usable for the most common width of drafting tape, painter's tape, etc. "
