I used a Canon Pixma inkjet printer to print colored round gloss labels for the individual product name and ingredients list. Then, I used a Brother laser printer to print tamper-proof labels (normally intended for lip balm) for a standardized jar label with my store name and contact info. These are 4oz plastic PET jars holding 5oz weight of an Awapuhi Seaberry emulsified sugar scrub.
I used Maestro to create my labels.
