Count the number of people in your household who use a mug regularly, then multiply this by the number of mugs they use in a day, and then increase that by one plus the number of days between running your dishwasher, or otherwise washing dishes. The amount you come up with is the base number of mugs you need in your home for regular use. Below are two examples to help you understand.
Example 1: If two people in your home regularly drink coffee or tea each morning, and you both only use one mug per day, and you run your dishwasher daily, then you need 2x1x2 mugs, meaning, 4 mugs. It works out that you need two mugs to drink from, and two in the dishwasher, and you’re set. 4 custom mugs with your favorite pictures or image by us can cost 20,000 won / $16.
Example 2: Two people in your house drink tea regularly, and both of you drink two cups a day in a fresh mug each time, and you run your dishwasher every two days. Then you should multiply 2x2x3, and you need 12 mugs. 12 custom mugs with your favorite pictures or image by us can cost 45,000 won / $36.
