The Cut Glencairn Glass is a handmade and hand cut crystal item. Each glass is individually crafted and as with all handmade pieces, they will vary slightly from piece to piece. No two can ever be identical and may reveal slight variations. Even by hand, all items are produced within tight tolerances and to the highest industry standards to provide an exceptional experience in crystal appreciation. Small variations in these cut glasses are the result of traditional, skilled hand craftsmanship, incomparable to mass automatic production. Acceptable examples of these imperfections can be found in the FAQs section of our website.
