About store.

This store is a reincarnation of a shop based in Russia with a long and very good history. Almost 200 positive feedback, 100% rating and more than 5 years of work. All this was changed in one moment... However, life is still going and I am with my friend from the US opening a new shop with stock in the US.

So... I am sure that it will be good for my old and new customers, because now we can ship faster and provide additional services such as preorders, reserves from transit etc.

For more information and updates, please feel free to follow us on Facebook and Telegram (transit lists, shipping updates, datasheets for tubes etc.). 

From the owner.

Thank you for visiting my store.

 If you are interested in more quantity than available in the current listing, feel free to ask me (eBay rules in some countries forbid displaying more than 9 pcs).

Also, do not forget to visit my store and subscribe for updates, coupons and sales.  

Sincerely, M.S.
