Every single board manufactured by TRIPSTIX is handmade. Therefore, it can happen that a board lies outside a strictly defined tolerance range of various quality criteria. This can manifest itself in a small optical defect, a minimal deviation from the processing specifications, etc. Nevertheless, the boards are fully ready for use.
We at TRIPSTIX believe that also such products deserve to be used. This saves resources and offers also the smaller purse the possibility of a nearly perfect high-performance board. For this reason we sell the boards as B-grades.
If you are interested in such a board, please send us an email to email@example.com.
