Sent a tangled lump of pieces of 6 kinds of braid in a simple thin package-pipets! Everything is confused-confused, long had to unwrap a ball with tied knots. Cuts with braid with beads in places crumbled. In addition, instead of ordered 200 cm was only 188 cm. Another 4 types of braid were also smaller in size as much as 20-30 cm. Disgusting thief service! I will not buy more here and i do not advise you.
Great! Thank you very much!
Adjusted to what was asked
Shipping time was little over a month to US. Good quality product.
