If you are new to using unmounted rubber stamps then these stamps from Woodware are a great way to start & offer excellent value for money.
The Clear stamps are so easy to use - you simply peel them off of the sheet - place onto an acrylic block and then simply stamp. The added advantage of these is that you can see exactly where you are stamping.
When you have finished simply clean your stamp & place back onto the sheet- couldnt be easier.
