One kit per bench that bands. A second bench needs its own tool, not a longer coil.
A strapping kit is the starting set: the tool and the strap, for a desk that is not banding yet. The page for Strapping kits is where Packaging Wholesale shows that line.
The published limit, if there is one
Kits are listed apart from loose strapping.
A coil on its own assumes you already have the tensioner and the seals.

The first order says kit. The next orders say coil and seals.
A Packaging Wholesale basket with Strapping kits still leaves the same day if it is placed by 3pm. The terms aim for 5.30pm the next working day. A 1 to 3 day courier is also described, depending on the lines.
Open Strapping kits when you already know this line. A kit is one set. The product page says what is in it. Do not assume spare coils. Packaging Wholesale will still dispatch an order placed by 3pm on the same day.
