The delivery was ULTRA FAST. The product was very well packaged. The elastic has pretty colors, they do not smell bad and are resistant. For now, I have only tested elastic solid color, I have not tested the two-tone elastic. I have only one small disappointment regarding the job that I was sent: contrary to the description, it is not compatible with rainbow loom trades, the studs are spaced a few millimeters less and craft is less high than the rainbow loom. In addition, the top of the studs is sharp because they are not trimmed. The seller has been reactive by responding quickly to my e mail claim, but to date, it has not solved.
