Always Use Top Quality Materials for your Packaging.
We all know how exciting it is to receive parcels - packages only to open it and not even find a thank you note...
You have probably received parcels wrapped in terrible conditions, I know I have with no sign of a thank you slip or anything.
I always buy the best jiffy bubble envelopes to send my items in and always insert a compliment slip, I recommend you do the same, this shows my customers that I care and they are more likely to buy from me again.
Remember- It;s the customer who pays for P+P so give them good quality.
