This is refined rosin. Suitable for ballet, musical instruments, woodworking, etc. As shown in the photos, it contains a mixture of powder, granules, and lumps. The size of the lumps varies. Please use the images as a reference. The lumps can be crushed by lightly tapping them with a wooden hammer. When crushing, dust will fly, so it is recommended to do so while the rosin is in a bag. Due to manufacturing reasons, the amount is slightly more than 50g, so please be aware of this. 100% pine resin (rosin)
