I had a bakery and enjoyed making these many times

Lot of 4 molds

This mold company is no longer in business

Takes a standard 4" lollipop stick  (not included)  Place in refrigerator, add some details when mold comes out, and is room temperature. 

These have been in storage, wash with warm soapy water before using. Never put hot items in molds, or in dishwasher.
