Compared to cheaper spacers that I've bought in the past on ebay, these have deep internal threads so you get a strong connection.

These are well made with a good standard of finish. They cover a useful range of sizes, well worth having in my photo bits box.

getting them apart

They arrived screwed together and could not be unscrewed by hand. Placed in the freezer for 20 minutes and then placed end on in a saucer that had hot water to a depth of 5 mm. After 30 seconds each ring in turn could be undone by hand. Spacers are very good value for the money

Nice and smooth. Just don't overtighten them, they will seize up! But that goes for all short extensions
