Personalized Black Leather Flask Wood Box Set- Groomsmen Gift- Groomsman Whiskey Gifts For Men, Custom Engraved Hip Flasks, Rustic Customized Gold Vegan Leather Wrapped #304 Steel 6 oz We believe in making great products. That's why we have our flasks manufactured exclusively for our company with extra thick 5mil, premium 18/8 grade #304 stainless steel. This makes a flask that is both highly durable & resists denting as well as rust/corrosion. #304 grade steel has 20-30 times more corrosion resistance than #201 steel - our flasks are true stainless steel and do not rust even under heavy use! Our flasks are professionally wrapped with vegan, scratch and water resistant leather, then engraved with extreme precision by our state-of-the-art laser, creating a deep black engraving in your design of choice. The resulting imprint is amazingly crisp and very durable - perfect for frequent use! Engraving is forever! The engraving is permanent, and made by a laser (awesome) so it will never rub off, fade, or peel. We can engrave any text - so let your imagination soar! Customize w/ any text! Choose from any of our design templates, located in the last image of this listing. Personalize with up to 4 lines, each up to 30 characters. We can engrave any text, simply enter your info in the text boxes and we will engrave it in the corresponding position.
