Success Story: A Custom Order from a Major Crafts Retailer

A major US crafts and floral supplies chain selected our glass tubes with cork, featuring a custom-colored cork stopper and a frosted glass finish. The custom product achieved massive success because its scientific design led to online sales growth of 500% in the “Vintage Pharmacist” category and the product sold 98% of its stock at retail locations during the first quarter. The supplier placed an additional order for 480,000 glass tubes because the market response to the product exceeded all expectations.
