Hello All!

I just have a quick question that I could not answer by searching. I have a Plisson Pour L'Occitane brush and love the knot. Unfortunately, the "wooden" handle has begun to bubble up around the metal cup. I have seen threads where people cut away the handle from the metal cup, and place the knot into a higher quality handle. I would like to have a crack at it, but wanted to order the handle prior to taking the brush out of commission.

Does anyone happen to know the dimensions of the metal cup that the knot sits in? I have measured the diameter at ~22mm, but really need the depth. Any assistance would be greatly appreciated.
