Designed specifically for the CHANEL Old Medium Boy Bag, this lightweight base shaper creates a smooth and even foundation at the bottom of your handbag. It helps support the bag’s natural structure, reduce visible base sagging and protect the interior lining from direct pressure and friction caused by everyday contents.
Designed for the following handbag:
CHANEL Old Medium Boy Bag
Approximate bag dimensions: 15 cm high × 25 cm wide × 9 cm deep
The fitted base shaper sits discreetly at the bottom of the Boy Bag, helping distribute everyday contents across a flatter surface. It provides targeted support where the handbag needs it most without adding the pockets, dividers or bulk of a full bag organizer.
Made from lightweight premium faux leather, the base shaper features a smooth finish and softly rounded corners designed to sit comfortably against the handbag lining. Multiple color options are available so you can coordinate the base shaper with the interior of your bag.
Please confirm that your handbag is the CHANEL Old Medium Boy Bag measuring approximately 25 cm wide before ordering. The Small, New Medium and Large Boy Bag models have different internal base dimensions and require their own fitted base shapers.
A base shaper provides ongoing support at the bottom of the handbag, but it cannot reverse existing creasing, stretching, sagging or material wear.
This listing is for one base shaper only. The handbag and other accessories shown in the images are not included.

I like that edges of the base shaper are rounded and don’t cut through the handbag interior.
The product is very high quality. And no sharp edge. I ordered for both of my chanel bags. I love them!
