Detail 01
.4 mm thickness
The thin option. Keeps the beak close to bare, so embouchure and response stay near unpatched.

BGMouthpiece Patches .4 mm Small Clear

Independent shopping perspective
The Korena take
Thin stick-on patches for the top of a mouthpiece beak. For players who want tooth grip and bite protection without changing how the mouthpiece feels.
Strong match
Who this is for
- Players who want tooth grip with almost no added thickness
- Protecting a beak from tooth marks and wear
- Clarinet, soprano and many alto beaks, which the small size fits
Consider the trade-offs
When to look elsewhere
- Players wanting cushioned bite relief — 0.4 mm pads very little
- Wide tenor or baritone beaks the small size won't fully cover
- Anyone unwilling to reapply as patches wear through
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
Small size
Cut for narrower beaks. On a large tenor or bari piece it can leave the edges exposed.
Detail 03
Clear
Nearly invisible on a dark mouthpiece, so a patched piece still looks clean. No effect on feel.
Detail 04
Stick-on patch
Needs a clean, dry beak to seat. Oil or saliva film and it lifts at the corner within days.
Detail 05
Under $12
A consumable. Budget for replacing them regularly rather than expecting one to last.
Final check
Know before you order
- 01Wipe and dry the beak first — residue is why patches peel early
- 02Mouthpiece not included; this is the patch only
- 03Measure your beak width — small won't span a wide tenor or bari piece
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will 0.4 mm change my sound?
Less than a thicker patch. At 0.4 mm the beak stays close to its bare profile, so embouchure and response shift very little. Thicker patches are the ones players notice.
02Will these fit a clarinet mouthpiece?
Small is the size range that suits narrower beaks like clarinet and soprano. Check your beak against the patch before applying — once it's stuck down, repositioning it usually ruins it.
03How long does one last?
Depends how hard you bite and how much you play. They wear through at the tooth contact point, which is why they're sold as a consumable rather than a permanent fix.
04Do they come off cleanly?
They peel off. Any adhesive film left behind wipes away before you apply the next one — clean the beak fully or the new patch won't seat.
