This CHANEL Medium Classic Flap 25cm base shaper is designed specifically for the CHANEL 11.12 Medium Classic Flap in the 25 cm size. It sits flat at the bottom of the bag to provide a more even foundation, help reduce base sagging and create a lightweight barrier between everyday items and the lining.
Because it supports only the bottom of the handbag, the base shaper preserves more interior room than a full organiser. There are no pockets or side panels, and it can be easily removed whenever additional base support is not required.
Designed for:
CHANEL 11.12 Medium Classic Flap — 25 cm
Approximate bag dimensions: 15.5 × 25.5 × 6.5 cm
The Medium Classic Flap has different internal dimensions from other Classic Flap sizes, so choosing the correct model is important for a suitable fit. If your handbag is a different size, view the CHANEL Small Classic Flap base shaper for the 23 cm version or the CHANEL Large/Jumbo Classic Double Flap base shaper.
A correctly fitted base shaper should sit flat at the bottom of the handbag without bending, moving excessively or pressing firmly against the sides. Please compare your exact handbag model, size and internal base measurements with those listed on this product page before ordering.
This removable insert can help create a flatter foundation and provide a lightweight layer between everyday contents and the bottom lining. It cannot prevent every sign of wear, rubbing, sagging or changes caused by regular handbag use.

Good quality base shaper for my chanel medium classic flap.
Awesome base shaper
Purchased two of these for my medium Chanel classic flap handbags. I knew they would fit perfectly based on previous purchases of several base shapers for other Chanel and Hermes handbags. They offered great support and have corrected one of my handbags that was slouching forward. The variety of colors match the colors of my handbags. I now only buy handbag shapers from M boutique.
I love it great quality I have purchase that bag shaper for all my handbags and my purses look amazing. Great quality. Amazing packaging , great customer service I highly recommend them.
