Pencil cutters 40mm 45mm Our cutters/stamps are made of PLA filament which is a durable material but please be gentle. PLA is a biodegradable plastic made from renewable, natural resources. Wash with warm water & Soap. A soft toothbrush also can help in cleaning fine areas of the cutter. Do not put in the Dishwasher or expose to heat Although these stamps/cutters were designed with clay-makers in mind, they are food safe & can be used for a variety of materials including Polymer Clay, Cookie dough, Fondant, Ceramics, soap stamps, pottery stamps etc… Roll your clay on a ceramic tile so it sticks to the tile, Cold clay & a cold tile do help especially with detailed or embossed cutters. Dip your cutter in corn starch to help ensure the clay doesn’t stick to your cutter. Some cutters may do well with a little water to help prevent sticking. You have to find what works best for you & the cutter you are using. Clean tools are always a good idea! I usually keep a baby wipes handy as they are helpful in cleaning. Press the cutter into your clay gently but firmly & maybe wiggle it a little to help get off excess clay. Having a water spray bottle handle is also helpful to clean my blades as it helps to keep shapes from being distorted. Most of all have fun & let your creative side come out!
