18mm Short Glass Concentrate Nail

To increase the life span of your Boro Silicate Concentrate Nail, remember to slowly heat the nail when it hasn't been used for a while. Heat will expand the glass and when heated too quickly the glass will expand too quickly which might crack the nail. Also, when applying concentrates don't tap your dabber against the divited head to hard which might also result in cracking the nail.
