A small glassy or ceramic mug would not cost you more than $10 per piece. Either you can go for personalized mugs and print your guest’s family name on that or select a unique designed pattern mug for a housewarming party favor.
The copper mug is the alternative housewarming party favor for Copper Bottle. If you aren’t able to find a decent copper bottle, go for the copper mugs. They are great as much as the copper bottles are and offering equivalent health benefits.
