Not bad for really affordable collets. Each collet is individually lube wrapped and in its own mini-case with size marking. The fit is slightly tight for the designated size but a little push will work.

Wish they came in one organized case with markings on them but nice price and seem to be good quality.

For the price this is a great deal. The collets had burs/ shavings inside them and needed a little cleaning out. Besides that we like them for the price and they are in the machine running.
