150 mm x 150 mm x 6 mm thick.
Thick enough to soak in oil.
Used when using bamboo skin baren. If you soak the felt part of this product in oil and place a bar on top of it, a small amount of oil will stick to it, making the baren slippery and making it easier to print. This product is convenient for applying the right amount of oil to the baren, and is a must-have for advanced users. This product is also recommended for those who use bearing ballens.
