I am wanting to get this engraved with someone's initials. What line do I put the letters on? There are options for up to 4 lines of writing. I would like the initials centered on the back of the flask. Thank you.
1 Answer
You can just enter them on line 1, we'll center them automatically.

I want 2 letters initial (RH) on it on front. Does it go on the clear place or stein less steel part? What size of the font is the best?
1 Answer
The engraving goes on the back of the flask. You can use the personalization preview feature to see what the engraving will look like. Font size 70 looks very good for initials.

Highly recommend Executive Gift Shop
January 30, 2015
I have purchased three different items from this store online. The shipping is alway quick and the product is always as described. They offer free engraving on most items,
What is really great is the ease of communication with them. I have ask several questions in the past on some of the items i purchased and i have received a response from
them in just a few minutes. I would highly recommend this Shoppe for its quality, pricing and return policy if you are not completely satisfied.

ProsI am a 73 year old senior citizen, for me ordering by computer is like trying to figure out Einstein's theory, but they make it simple and the communication is so very helpful.
