This CHANEL Old Medium Boy Bag base shaper is designed specifically for the Old Medium version of the CHANEL Boy Bag, measuring approximately 25 cm wide. It sits flat at the bottom of the handbag to create a more even, stable foundation, provide targeted base support and help distribute the weight of everyday items more evenly.
Unlike a full bag organiser, this removable insert supports only the bottom of the bag without adding pockets, side panels or bulky compartments. This helps preserve usable interior space while providing support where everyday contents are carried.
Designed for:
CHANEL Old Medium Boy Bag — 25 cm
Approximate bag dimensions: 15 × 25 × 9 cm
The Old Medium Boy Bag is different from the Small and New Medium versions, and their base shapers should not be treated as interchangeable. If your handbag is a different size, choose the CHANEL Small Boy Bag base shaper or the CHANEL New Medium Boy Bag 28cm base shaper instead.
A correctly fitted base shaper should sit flat at the bottom of the handbag without bending, shifting excessively or pressing firmly against the sides. Always confirm your exact Boy Bag model, size and internal base measurements before ordering.
The insert can help create a flatter foundation and distribute everyday contents across the base while providing a lightweight layer between your belongings and the bottom lining. It cannot prevent every sign of sagging, rubbing, creasing, wear or changes caused by regular handbag use.

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!
