Extend the Life of Your Baby's Favourite Bodysuits

Made from soft, gentle cotton, these snap extenders simply attach between the existing snaps on any standard triangle-crotch romper or bodysuit, adding the length your growing baby needs.

Important Button Note

Due to the variety of snap button specifications used across different baby garment brands (sizes may range from 0.8 to 0.95 cm), the extender snaps may occasionally feel slightly tight or loose. If needed, use the tip of a pair of scissors to gently adjust the snap teeth for a secure fit. This is a normal characteristic of universal extenders and is not a manufacturing defect.

A: These extenders are designed to be universal and fit most standard snap-button triangle-crotch rompers and bodysuits. However, snap button diameters can vary between brands (0.8–0.95 cm).
