MRL Mini Rollers have a rolling design face that is 10 mm (0.4 inch) across. MKM Mini Rollers are beautifully carved, have unique designs, release well, and have a smooth carved texture. MRL Mini Rollers are made from wood and finished with tung oil to ensure durability for many years of use. The Mini Rollers are easily cleaned with water and a soft toothbrush. All MKM MRL Mini Rollers are best rolled with the RH-2 Handle. The RH-2 splits apart to facilitate inserting a different MRL Roller. One RH-2 is all you need to use for any MRS or MRL roller. The RH-2 and MRL Rollers are sold separately.
