12 Pieces Coasters for Drinks, 4 Inch Black Slate Stone Coasters Bulk with Anti-Scratch Backing for Bar, Gifts, DIY, Laser Engraving, Kitchen, Home Decor, Square

These coasters are very nice and worked especially well for engraving. The surface engraved cleanly and gave a sharp, clear finish, making them ideal for custom designs. They also feel sturdy and do a good job protecting surfaces from drinks. Overall, a great set if you’re looking for coasters that can be personalised easily.

Excellent and came in time for a order I had a bit more expensive than my usual surplyer but I will say a better quality I will be getting more when needed

I find these, at the time of review, great value for money, a little over a pound for each. I used to buy from another source, and they were a bit thicker, but the price was more and I thought I'd give these a go. They engrave really well and out of many orders I've only had 2 or 3 that were either way too thin for me to sell, or too uneven. Can't complain at that. I use the really thin ones as testers. They arrive in a good secure box, bubbled wrapped 2 apiece. None have had any marks on them. I have only had two from several boxes that were unstable due to the felt feet being placed on the uneven bottom of the coaster, where the slate had formed in layers. The natural look is perfect for what I use, it's not too neat and not too rough. Even without any decoration they look very nice. I spray them with clear varnish for a more contrasting engraving. I have dropped one from a short distance onto my desk and it didn't damage or break, not that I would expect my finish products to be dropped, but it's nice to mention. Overall, I really recommend these if you plan to engrave them like I have.

Generally good quality. I've had no unusable items out of the two boxes that I've received. I doc a star as the feet are sometimes stuck on in rather random positions. Also, some of the slates have slightly smaller 'clean' areas for engraving so I have to check each one - would be nice if all had at least 90mm diameter clean area (most do but I you have to check).

Really pleased with these slate coasters. Received all without any breakages. Just wipe clean. All in all, very happy with my purchase.

Great for engravings

They are fine. Would advise that you sand them smooth and then apply lacquer before laser engraving for the best effect.

Heavy duty, nice finish, work well with xtool engraver

Parfait. Ardoise régulière et de bonne facture.

Le produit est de bonne qualité, l'ardoise a un très bon rendue une fois gravée. Le vendeur a expédié ma commande très rapidement.

Excellent.qualité parfaite, bien emballé, arrivé rapidement.je recommande ce vendeur.très satisfait.je commanderai à nouveau.de plus grandes quantités (100 pcs et plus) seraient géniales si le fournisseur pouvait? Merci.

Impossible de faire de la gravure profonde sur ces sous verres (ardoise de mauvais qualité).

Produit identique à l'annonce tout est parfait. Par contre la boîte c'est ouverte durant le transport, et une ardoise a été abîmer. Et d'autres ont eux quelques éclats. Merci de mieux protéger le colis pour de futur commande, en le livrant dans un carton épais et non dans un sachet pour éviter plus de casse.
