A cost effective way to create a tiling background for my project. I would have bought stainless fixing washers and screws if they were available in the size I require

Wow; ordered late afternoon and arrived within 24 hours. Magic is in the making. Still waiting for items from a major online retailer that is named after a South American rain forest and still to be advised that parts are available from a local depot of a national store that you would think only sells fixing screws.
All parts were as ordered. Still to open the insulation box.
Opportunity for improvement, yes; there was a 1/2 inch split in the plastic bag that had some items, none of which were sharp. A small item could have gotten lost. Possibily a transit issue.

Thank you so much for taking the time to leave an excellent rating. We really appreciate your business. Please let us know what we can do for you in the future.
