These are a few kits of some of my favorite tubes (the ones that I travel with). Each one is assembled by hand. Gels are protected with an additional layer inside the tube. The included caps are perfect to bounce back the light (full caps) and/or to addaccessorieson top of the tubes (feathers, pipe cleaners, sparklers). I also include with most kits a double-cap which allows you to easilycreate stripes. I teach how to use these tubes on myYoutube channeland in myprivate learning group.
