Druid proudly launches DEBUT ULTRA, the lightest ever series weighted from 1.9 grams, with 5G version less than 2.5 grams. From LEGO around 20 grams to ULTRA less than 2 grams, the weight range is exactly correlated with the species of hummingbird. What has changed is the weight, what has not changed is the function package as DEBUT.
