Don’t buy from them
I bought a Flying V guitar kit, and the quality of the neck I very low : more than half of the frets protrude and extend beyond the fingerboard. Two professional luthiers to whom I showed the instrument indicated, based on their expertise, that the work had defects requiring a complete refret, and that in its current state it was unplayable according to their evaluation. The seller, for their part, stated that they did not see any issue, despite the photos, videos, and a written statement from the luthier that I provided.
