Romper extenders

These romper extenders have 8mm, 9mm, or 10mm buttons. Combinations are available if you need all sizes. The extenders come in sets in random prints.

8mm: set of 3

9mm: set of 3

10mm: set of 2

8+9mm: set of 4

8 + 9 + 10 mm: set of 3

The rompers in the BolleBIllen shop usually have 9mm buttons, but they are for washable diapers, so you don't have to use them for this.

For example, the following rompers fit with 9mm:

H&M, Dilling, Miffy, most of Zeeman, most of C&A, Noukies, Duns, Prénatal, Bambino

Hema: responsible cotton plain and print multipacks, organic cotton plain, wrap rompers, rib jersey.

The following rompers will probably fit with 8mm:

A few from Zeeman, a few from C&A, petit bateau, Little Woody, Ne'Beans, Lupilu.

HEMA: romper dresses, organic light blue, army print, car print, zebra print, rompers with lace, bamboo.

I haven't tested any other brands yet, so please let me know what fits and what doesn't!
