What role does the hidden finger hole on the sleeve play?
The t-shirt sleeve description mentions the detail of a hidden finger hole, making one wonder what its purpose is.
You can hook your finger through to secure the sleeve over the back of your hand, or hide the hole to keep it neat like a shirt cuff.
HATCHINGROOM's double sleeve t-shirt features a contrasting outer and inner sleeve structure. The outside has a neat cuff shape like a shirt, but a finger hole where you can insert your finger is hidden along the inner seam[1][2].
There are two ways to wear the wrists. When you hook your thumb through the finger hole, the sleeve is fixed covering the back of your hand, preventing the sleeve from riding up your arm when layering outerwear. It is also useful when you want to cover up to the back of your hand.
When you take your finger out, the hole is not exposed to the outside, arranging smoothly like a regular long sleeve. Matte poly buttons without gloss are attached to the sleeve ends[3], allowing you to tighten or loosen the sleeve width to fit your wrist even with the finger hole hidden.

The length of the finger hole cut line and whether it has elasticity have not yet been confirmed.
