Not quite choggy,the only part of the match kit that should be telescopic is the number one (thinnest piece)
Some cheaper match kits are all telescopic.
See if the number 2 and 3 fit together if they don’t then it must be telescopic.
As for elastication,most people use a short piece of elastic on elastics smaller than a size 8,just elasticating,the number 1 and 2 sections of a match kit,therefore assuming your match kit is putover (between sections 2 and 3)you can use a winder bung.
On larger elastics in your power kit,fitting elastic through the whole kit is advisable,again using a winder bung.
