The regular Slimline
box holds 104 small spools only, of various brands. The Universal Slimline
holds 64 kingsize spools, as well as small spools, of various brands. Neither will hold the mini-cones. In any Sulky Slimline Storage Box, easily remove a spool using the exclusive, patented, individual lifting tabs. Spools won't fall out no matter whether the box is freestanding and partially opened near your machine
or fully opened and hung on a wall.
In addition to the empty boxes, there are dozens of filled or partly filled collections of Sulky threads also available in these boxes.
