I bought test tubes to start cuttings last year. There are sits online where you can get them by the dozen and they are not too expensive. Also, the holders are sold there also. I found it very easy to use them but the space I needed for the holders became a problem. I am sorry I do not remember the links to the sites but if you google test tubes you can find one I am sure.
The ones I bought are the regular ones they use in labs and they comes in different sizes.
