Our engraved reclaimed wine bottle tumblers are recycled from cobalt blue Riesling wine bottles and meticulously sand-carved by hand with your monogram or your company logo. Create a beautiful table with our custom cobalt blue drinking glasses or give a unique gift to that person who has everything. Our wine bottle drinking glasses hold approximately 12 oz and measure 4.5" high by 3" wide. The lip of the re-purposed wine bottle has been beautifully and carefully polished to a smooth edge for drinking. Dishwasher safe.
