About Copic Air Grip
If tightened firmly to the adapter, air leaks occur, and it sprays even without pulling the trigger.
It seems usable if the tightening is adjusted, but since it is an old item, I recommend purchasing a new Copic Air Grip.
The pen mount part can be attached without any problems (confirmed with Copic Sketch).

Since the product is still being sold currently (^^;

This is an old item. There may be unseen deterioration, but please judge from the photos. Those who are sensitive to such things should refrain from purchasing. Thank you.
