I ordered in the larger size having read one review which said they came up rather small and that is quite common for stretchy jeans. However they are rather roomy on me so I decided to keep them (belted) for everyday use and ordered a second pair in my correct (normal) size and they fit perfectly, so I will save those for best. Very stylish, good accurate fit and most importantly great value for money.
Excellent idea for sealing envelopes. I shall be using them for sealing my wedding invitations. They are about the size of a 10p piece with peel-off sticky disc to adhere to envelopes. Service was very good - arrived promptly the next day as promised. Recommended.
