The KRs and KRm rollers are excellent for curving and straight linear decoration, as well as borders, dividing lines, and so on. Similar to other Kor products, they leave a very clear and distinct decoration in PMC and polymer clays (as well as natural clays). The patterns in the rollers release very easily from the clay with no pulled edges.
These rollers are quite small, with a design face measuring 5mm (KRs) or 10mm (KRm) across. The full roller with the axles is 2.0cm across and has a diameter of 17 to 18mm. The KRs and KRm rollers, like the Kor Stamps, Kor Texture Rollers, and Kor Polyclay Rollers, is made from a unique proprietary kind of black acrylic. Please take a look at the image of the relative sizes of the tools in order to understand their relative scale.
All the KRm and KRs rollers fit on the RH-2 handle. The RH-2 handle greatly facilitates using these very small rollers. The RH-2 handle splits in half so a roller of one design can be removed, and a different roller can be attached. So you only need to purchase one handle no matter how many KRm and KRs rollers you have.
Due to their small size, the KRs and KRm rollers are best used with the RH-2 Handle. All KRm and KRs rollers can be easily changed out with the RH-2 Handle.
