New quality tube for K40

[Tech_Marco]

I have ordered 25x 700mm and 25x 850mm laser tube from a well know laser manufacturer in China. The company is very well known of making small tube and quality is not an issue.

I have request 5 of each to ship to me through DHL and I should receive it sometimes on next week. Price will be jack up $35 more because the company asked for more. These tubes are much better than those tube you found on eBay with less divergence and life span.

I'll take back order now

Regards,
Marco
