Monograms will be 2.5-3". To apply, rub a credit card over the top and peel the top clear layer. Monogram should adhere to this layer. Place monogram onto your object and smooth again with credit card before peeling the clear top layer off. If adhering to a cup, let sit for at least a day before use (the longer, the better!). HAND WASH ONLY. Do not put in the dishwasher or leave in standing water.
