Will Bottle Bumpers fit bottles that aren't Koh's?
⚠ Fit on non-Koh bottles isn't guaranteed
Bumpers are designed around the specific base geometry of Atomiser Spray Bottle and Foaming Spray Bottle. If a third-party bottle has a base close to 5.7 to 5.9 cm in diameter, a bumper may stretch to fit, but grip and stability aren't guaranteed and bumpers may slide or feel loose.
Tip before buying for another bottle. Measure your bottle's base diameter. If it sits in the 5.7 to 5.9 cm range, a bumper will likely grip. Outside that range, fit is unlikely to hold.
Soft food-grade silicone. Colour-coded for kitchen, bathroom, universal, and stain-remover use.
