This is the part for the hardness display window of pg5. * Made from a plum tree branch. * There is no hole for the hardness display window. * The surface is coated with beeswax wax. * There are steps and gaps between this part and the pg5 body. * It is made of wood and is thin, so I am not very confident in its durability. I have used a Somei Yoshino version for over six months without any cracks, but there may be individual differences. * It is difficult to attach to the pg5 as it is tight. The pg5 body is not included. Price is not negotiable. Please understand that this is handmade before purchasing. No. 1
