Hit or miss products and customer service
TLDR: Ersa does not care about your health or user experience past the “pay now” button Quality of product is hit or miss. Some sets are definitely drop ships that can be found on Temu for ~$3, others are original designs that feel sturdier. They do not warn customers of the dangers of using their solid glue gel. Improper handling of this product can result in a lifelong allergy to acrylates. Their customer service is responsive but rarely helpful and each interaction takes at least 3-5 email exchanges to make real progress. I have spent several hundreds of dollars on this site to date but after my most recent experience with their customer service team, I will be supporting independent artists instead. ———————————————————— UPDATE: 2-Star to 1-Star after Ersa’s reply, with their original response copy and pasted at bottom: The customer situation they are replying to below is not mine. I will not comment on originality of designs, but after purchasing a variety of sets from your website, I can say that the quality varies greatly within Ersa’s catalogue. More importantly, there are extensive studies that link acrylates to contact dermatitis. For example: Kucharczyk M, Słowik-Rylska M, Cyran-Stemplewska S, Gieroń M, Nowak-Starz G, Kręcisz B. Acrylates as a significant cause of allergic contact dermatitis: new sources of exposure. Postepy Dermatol Alergol. 2021 Aug;38(4):555-560. doi: 10.5114/ada.2020.95848. Epub 2021 Sep 15. PMID: 34658693; PMCID: PMC8501444. This site’s dismissive attitude surrounding a serious health risk is more damaging than any lacking customer service team or questionable product. I am not pursuing any type of refund, I am just leaving a review and warning for any future customers so they don’t have to go through what I have. ——————————————————- Ersa’s original reply copy and pasted below: “Dear Customer, We appreciate all feedback and would like to provide a clear account of the situation. After your purchase, you reported that one pinky nail piece was missing. We promptly arranged a replacement, which was delivered on January 27th, as confirmed by tracking information. The product arrived complete and in perfect condition. Despite this, you requested a full refund, even though the item was intact and fully delivered. We consider this request to be unreasonable and not representative of normal customer expectations. You also mentioned finding similar products for only a few euros on other platforms. While we respect every customer’s choice of where to shop, our original designs are hand-crafted and frequently copied or imitated online. In fact, unauthorized replicas exist, and we have even encountered websites selling counterfeit versions of our products. Our loyal customers appreciate and trust the authenticity and quality of our handmade items. Regarding your claim about potential allergic reactions to our adhesive, no formal medical or lab documentation was provided. We have offered multiple times to review proper evidence, such as a hospital report or certified lab test, but none was supplied. Refunds cannot be issued based on unverified claims. We take pride in the craftsmanship, originality, and quality of our products, and we remain committed to providing all customers with honest, transparent service. We hope this clarifies the situation and reinforces the value and authenticity of our handmade products. Sincerely, Ersa Nails” ——————————————————- UPDATE 2: Ersa… your own website advertises that your product contains acrylates. Look up your product page for “Solid Nail Glue Gel”, which lists the following ingredients: Acrylates, Polymethyl methacrylate, Copolymer. I would stop selling these products. They’re listed for $3.99. I doubt it’s your largest profit generator by a mile but definitely has risk and exposure for the company.

We take product safety and customer health very seriously. Regarding your claim about our product causing contact dermatitis related to acrylic substances, we would greatly appreciate it if you could provide official, evidence-based documentation or test reports that clearly prove our product contains Acrylates and is the direct cause of your condition. We cannot respond to or accept unsubstantiated allegations or rumors. If you have genuine concerns supported by factual evidence, we are willing to look into this matter thoroughly and assist you accordingly. Thank you for your understanding. ——————————————————- All ingredients are clearly listed on our website. If someone knows they are allergic to a certain ingredient and still chooses to buy the product, any reaction is entirely their responsibility. Using this as an excuse to leave negative reviews or demand that we stop selling our products is blatant malicious coercion, and we will not tolerate it.
