MRX Mini Rollers have a rolling design face that is 2 cm (0.8 inch) across. MKM Mini Rollers are beautifully carved, have unique designs, release well, and have a smooth carved texture. MRX 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 MRX Mini Rollers are best rolled with the RH-2 Handle. The RH-2 splits apart to facilitate inserting a different MRS, MRL, or MRX Roller. One RH-2 is all you need to use for any MRS, MRL or MRX roller. The RH-2 and Rollers are sold separately.
