I had this stamp set, it was a double mounted, 2 step stampin' set from a mini a year or two back. I have since sold it, as it retired. However, I recently found a stamp that belongs with this set that had been mistakenly put with another set. I have been through my eBay listings, but can't find it, so I thought I would put the call out to my blog readers in case it was you I sold the set to! My sincere apologies, I usually count the stamps - although it is possible your Soft Summer set has a stamp that doesn't belong inside the case!!
I'd love to return the little lost stamp, so please get in touch if you are the new owner :)
