A vertical organizer for tape! I specifically designed this with packing tape in mind, but it will fit anything with a diameter of 110 mm or less, e.g. masking tape. If using for duct tape, I'd recommend measuring your roll first; mine (Gorilla brand) was too large in diameter.

Will hold up to 5 rolls of packing tape, likely around double that if using for masking tape or other rolls ~1" wide.
