These swatches are a fantastic idea! The colours are very similar to those you see on the computer screen but seeing them in the flesh definitely helped us to pick the exact shade we needed and having something physical to take to the shops has helped us to bring other non-Swagger&Swoon products in line with the shade that we are matching to.
The swatches arrived quickly and were very reasonable.
The only downside was that we ordered three shades and while each one was labelled with its serial number, we then had to match the serial numbers to the invoice to know which shade was which. It really wasn't a problem at all but I suppose printing the names on the swatch cards would have made things that little bit easier ;)
