Description:Our pipemakers make a custom made mouthpiece for your old pipe in black acrylic without stamp/marking. Acrylic versus rubber stemThe acrylic stem is the more "modern" type and it keeps the shinny black colour. Some still prefer the rubber mouth piece and claim its not as "crispy" as the acrylic, but its different from person to person. The rubber stem gets grey/green if you dont maintain it. We recommend Obsidan Stem Oil for rubber and cumberland stems.Its a great help if you send us the old mouthpiece. We can do the original mark on most of the pipe brands (factory pipes). If you wish this please make a comment about that in the order. We reserve the right to not do it if we don't have the specific original mark.How?You finish your order here and pay here. Then you send us the pipe with the old stem. Remember to leave a note or a print of the order confirmation so we have the adress etc.You can learn more about the different words used in the world of pipes here TAX FREE: Please note that if you are an outside EU citizen the VAT (20%) will be deducted the listed prices when/if you finish your order.
