※ Images after image 2 are of a set of 4. This is one piece cut into 4 equal parts. Each piece is 20x20x10mm thick. Can be used as insulators for audio equipment, vibration isolation, earthquake resistance, etc. After purchasing new, I cut them as shown in the images and store them in bags. When shipping, I will package them in a bag and cardboard as shown in image 6, and ship them in a brown envelope. Double-sided tape is attached to the bottom. The original powder has been removed. The cutting is done by an amateur, so it is uneven. Please accept some imperfections in the cutting. Price negotiations are not accepted for this product. Please see my profile for other shipping information. Audio DAC Amplifier Speakers DTM Audio Interface Insulator Vibration Isolation Earthquake Resistance
