Product Insights
The Le 31 Collar Extender Stud offers a simple way to gain a little extra room at the collar of a shirt, attaching by looping around the top button rather than clipping to collar points, making it compatible with standard and button-down collars. The adjustment mechanism relies on manually stretching the spring loop to add space, but this also introduces the main tradeoff: overstretching can permanently deform the loop, and the black dot finish is prone to chipping with friction or washing. Beyond its primary use, the same spring loop can double as a minimalist wrist ring, with the caveat that it lacks any clasp or size adjustment and shares the same permanent-stretch risk if forced. It is sold as a single stud for CA$9, not as a pair or multi-pack, and the only color option is assorted, which still delivers one black stud with a black dot.
Verified claims
- Attachment
- Attaches by looping around the shirt button, not clipping onto collar points.
- Collar compatibility
- Fits standard and button-down collars; only the top button engages.
- Stretch adjustment
- The stainless steel loop stretches to adapt to different shirt buttons, but pulling it farther than the buttonhole requires can permanently deform it.
- Black dot
- Black dot finish may chip with friction or washing.
- Wrist wear
- On the wrist the spring loop itself is the band — no clasp or size adjustment.
- Sold quantity
- One collar stud per CA$9 order — not a pair or multi-pack.
- Durability
- Unlike fixed plastic extenders, the steel loop stretches over varied buttons, but one user reports forcing it can permanently deform it.
- Wrist fit
- Same spring loop fits the wrist by stretching, but forcing it too wide can permanently deform it.
- Wrist styling
- At the wrist it reads as a slim metal loop with a black-dot badge; the dot finish can chip.
- Unit quantity
- One CA$9 purchase is a single stud, not a pair.
- Assorted label
- Assorted is the color option next to ONE SIZE: each order contains one black stud with the same black dot.
- Repairability
- The stretch spring loop is not replaceable; the entire stud is a single unit and is best considered disposable if the spring loses elasticity.
- Black dot finish
- The black dot is a surface-level finish rather than an embedded detail, and it may chip with friction or washing.
