The product is made of 3MM MDF. The back is completely double-sided. You can then mount it elsewhere with double-sided tape. Minute and hour hand models may have different patterns depending on the stock. INSTALLATION: Attach the included mounting template to the wall with a nail in the middle of the clock. Mark the locations with the help of the template and paste it on the wall, making sure it is flat and clean. Attach the mechanism to the middle part by removing the nut on the mechanism and tightening it to the middle part. Attach the minute and hour hands carefully. Take the template and hang the hub on which you mounted the mechanism on the wall.
