Ikea has a travel tube perfectly sized for a Simpson Wee Scot. An Omega "Bambino" also fits but unfortunately the handle of the Omega 11047 is just slightly too wide. The Art of Shaving small pure badger brush that comes with the $25 set is manageable if you don't close it completely, the hair rises slightly above the rim of the plastic insert. The vent holes at the top are in the shape of an "S" for Simpson. It comes in a set of two, on the second, the vent holes are in the shape of a "P", presumably for the Plisson version of the Wee Scot. A Palmolive shave stick would not fit. You can find them on the Ikea website under the name "Plats", however they are mislabeled as "salt & pepper shakers".
